PGRL1 is a transmembrane protein present in thylakoids of higher plants and algae. Arabidopsis plants lacking PGRL1 show perturbation of cyclic electron transport (CEF) around photosystem I (PSI), similar to PGR5-deficient plants. PGRL1 has been shown to interact physically with PGR5 and associate with PSI (DalCorso et al., 2008). In Chlamydomonas reinhardtii, PGRL1 is part of a protein supercomplex, composed of PSI with its own light-harvesting complex (LHCI), the photosystem II light-harvesting complex (LHCII), the cytochrome b6/f complex (Cyt b6f), ferredoxin (Fd)-NADPH oxidoreductase (FNR), responsible of the energy balance of the two photosystems and of the switch between thylakoid linear and cyclic electron transport (Iwai et al., 2010).

TROL (thylakoid rhodanase-like protein) is an integral membrane component associated to the photosynthetic apparatus of higher plants. TROL is involved in the final step of photosynthetic electron transport by binding a key energy-conversion enzyme ferredoxin: NADP+ oxidoreductase (FNR). This interaction enables direct transfer of photosynthetic electrons from iron-sulphur protein ferredoxin at the stromal site of photosystem I to FNR, which then hands over electrons to NADP+. TROL is located in two distinct chloroplast compartments – in the inner envelope of chloroplasts, in its precursor form; and in the thylakoid membranes, where it is processed completely. Alternative names: Protein THYLAKOID RHODANESE-LIKE1, Sulfurtransferase 4, AtStr4

TROL protein can be used as a chloroplast dual-localization marker: for the thylakoids (the major portion of the protein) and the chloroplastic inner envelope. Since the envelopes make a very small portion of the total membranes, the envelope form of TROL is detectable only when isolated envelopes are applied. For AgriseraECLBright and Agrisera matching secondary antibodies goat anti-rabbit HRP conjugated, dilution 1: 25 000 1h/RT incubation (AS09 602), anti-TROL antibodies can be used in dilution of 1:3000.Recommendation: 2 g chlorophyll/well.

Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. Higher plants also possess genes for significantly different, as yet uncharacterized Fd proteins, with extended C termini (FdCs). Whether these FdC proteins function as photosynthetic electron transfer proteins is not known. It has been suggested that FdC1 has a specific function in conditions of acceptor limitation at PSI, and channels electrons away from NADP(+) photoreduction.

Multi-subunit complex of cytb6/f is a crucial component for the photosynthetic electron transport chain of higher plants, green algae and cyanobacteria. This complex is catalyzing oxidation of quinols and the reduction the reduction of plastocyanin. This reaction allows to establish the proton force required for the ATP synthesis. Four major subunits build the complex: the petA gene product corresponding to a c-type cytochrome (cytf), the petB gene product corresponding to a b-type/c’-type cytochrome with three haems (cyt b6), the petD gene product (subunit IV, or suIV), and the petC gene product, corresponding to the Rieske/Iron/sulfur protein.

PsaG (PSI-G subunit of photosystem I) is a 11-kDa membrane protein that plays an important role in electron transport between plastocyanin and PSI and is involved in the stability of the PSI complex. PSI-G subunit is bound to PSI-B and is in contact with Lhca1. The protein inserts into thylakoids by a direct or "spontaneous" pathway that does not involve the activities of any known chloroplast protein-targeting machinery. PSI-G appears to be directly or indirectly involved in the interaction between Photosystem I and plastocyanin.

FNR (ferredoxin-NADP+-oxidoreductase) catalyzes reduction of NADP+ using Fd that has accepted electrons from photosystem II in the final step of linear photosynthetic electron transport. In higher plants FNRs are encoded by a small multiple gene family (two chloroplast-targeted FNR in Arabidopsis and rice and three isoenzymes in maize). All forms are evenly distributed between the thylakoids and stroma.

In some species minor cross reactions with some larger proteins are seen. These may contain related iron-sulfur binding motifs. Therefore size verification of the reacting band is required. Due to the small size of the protein, care should be taken to differentiate between chemiluminescent signal from PsaC and non-specific signals from chlotophylls or lipids if pigment is retained near the bottom of the blot.For the most optimal results use:thylakoid membranes or PSI particles, solubilized in a SDS sample buffer (final concentrations: 63 mM Tris HCl, 10% glycerol, 2% SDS, 0.0025% bromophenol blue) with 2.5% beta-mercaptoethanol at 85C for 2 minutes. The samples were spun softly, then the supernatant loaded. This product can be sold containing ProClin if requested.

Glutamine oxoglutarate aminotransferase (abbreviated as GOGAT) is an enzyme involved in synthesis of glutamate from glutamine and alpha-ketoglutarate. GOGAT has two forms in plants: ferredoxin-dependent GOGAT (Fd-GOGAT) and NADH-dependent GOGAT (NADH-GOGAT). 95% of GOGAT found in plants is the Fd-GOGAT type. Fd-GOGAT is encoded by two genes, glu1 and glu2 found on chromosomes 5 and 2 respectively (in Arabidopsis). Fd-GOGAT (both forms) is highly conserved among plants, red algae, and cyanobacteria.

KLH-conjugated synthetic peptide well conserved in known GOGAT sequences from different species including Arabidopsis thaliana Fd-GOGAT 1 Q9ZNZ7, At5g04140 and Fd-GOGAT 2 Q9T0P4, At2g41220
This antibody can be used as a plastidial marker for leaf material, not roots where levels of GOGAT are too low. A 40 kDa band present in A. thaliana sample is not competed away during antibody neutralization assay. In this assay free peptide used for antibody production is incubated together with anti-GOGAT antibodies. Due to the MW of this protein we suggest to use a gradient gel for protein separation and a longer transfer time.

The PsbH protein was originally named 10- or 9-kDa phosphoprotein in higher plant chloroplasts. It is encoded by the plastome in algae and higher plants. PsbH is also present in cyanobacteria, where it exhibits 56% amino acid identity with the corresponding protein from Arabidopsis. The protein contains 63–90 amino acids, depending on the species, with molecular masses between 7.0 and 9.9 kDa.PsbH is an intrinsic membrane protein with a single transmembrane helix and its N-terminal region has been suggested to be exposed to the stromal side of the thylakoid membrane. Presence of PsbH already present in etiolated tissue can indicate that the protein may be involved in early stages of PSII assembly.Obtained biochemical data from PSII complexes isolated from spinach suggest that PsbH, together with other PSII phosphoproteins, may be required for D1 protein turnover by regulating dimeric and monomeric PSII transition through their phosphorylation and dephosphorylation.

PsaH (PSI-H) is a conserved subunit of type I photosynthetic reaction centers (Photosystem I, PSI). PSI is an integral membrane multi-protein complex that catalyzes the electron transfer from plastocyanin (or cytochrome c6) to ferredoxin (or flavodoxin). Psa-H has been suggested to be involved in regulation of state1-state2 transitions. In plants and green algae Psa-H is nuclear encoded and imported post-translationally into the chloroplast where it inserts into the thylakoid membrane.

Cytochrome b559 (Cyt b559) is encoded by the chloroplast genes psbE and psbF and is comprised of two low molecular mass polypeptides, α and subunits, with molecular masses of 9 and 4 kDa, respectively. The Cyt b559 is closely associated with PSII in all oxygenic photosynthetic organisms. The α and subunits of the Cyt b559 are components of the minimal PSII reaction center complex that is still capable of primary charge separation In summary, both PsbE and PsbF are essential components for PSII assembly, and they are probably involved in electron transport mechanisms that help to protect PSII from photodamage.

This product can be sold containing proClin if requested.The anti-AtpB antibody will detect the mitochondrial form of the F1 ATP synthase subcomplex, as well as the chloroplastic CF1 Atp Synthase, and most known bacterial F-type Atp Synthases. Peptide used for antibody production is located in a beta sheet, which is partly exposed near the surface of the AtpB protein.
The psbA gene has been cloned from many species of plants, green algae, and cyanobacteria. The psbA gene is located in the chloroplast genome and encodes for the D1 protein, a core component of Photosystem II. PsbA/D1 is rapidly cycled under illumination in all oxygenic photobionts. Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples. Alternative names: 32 kDa thylakoid membrane protein, photosystem II protein D1.

Immunogen:
KLH-conjugated synthetic peptide derived from available plant, algal and cyanobacterial PsbA sequences, including Arabidopsis thaliana UniProt: A4QJR4, TAIR: AtCg00020 , Oryza sativa P0C434, Populus alba Q14FH6, Physcomitrella patens Q6YXN7, Chlamydomonas reinhardtii P07753, Synechocystis sp. P14660 and many others
The antibody is appropriate for detecting both, 24 kDa or the 10 kDa C-terminal fragments, whichever is generated under given treatment conditions. In our analysis we have seen both, ca. 24 kDa and ca. 10 kDa fragments from different samples, depending on treatments and isolation procedures.Rabbit anti-PsbA antibody can detect more than one band of PsbA protein, e.g. precursor and mature protein as compare to the chicken anti-PsbA antibodies AS01 016.This antibody will detect the phosphorylated form of D1 as an alternate band to the main band on a high resolution gel.The antibody will bind to cross-linked proteins: D1/D2, D1/cyt b559, D1/CP43.

Special application note:
Due to biology of PsbA (D1) protein a number of degradation products can apprear in a sample and may be observed when using anti-PsbA antibodies, including products having apparent molecular weights of 24kDa and 16kDa. D1 degradation is a complex set of events and the products observed can be influenced by both the extraction procedure and the physiology of the cells prior to harvest. Third, cross-linking may occur between D1 and cytochrome b559, shifting the protein higher in the gel. In cyanobacteria (PCC7942), three different bands were competed out by preincubating the antibody with the PsbA free peptide, indicating that all bands are indeed PsbA and its precursors or breakdown products. Competition assays were also performed with spinach and Chlamydomonas, confirming the identity of PsbA bands.Anti-PsbA antibodies will not detect D2 protein, as the peptide used to generate PsbA antibodies has no homology to the D2 sequence.

Special application note:
Due to biology of PsbA (D1) protein a number of degradation products can apprear in a sample and may be observed when using anti-PsbA antibodies, including products having apparent molecular weights of 24kDa and 16kDa. D1 degradation is a complex set of events and the products observed can be influenced by both the extraction procedure and the physiology of the cells prior to harvest. Third, cross-linking may occur between D1 and cytochrome b559, shifting the protein higher in the gel. In cyanobacteria (PCC7942), three different bands were competed out by preincubating the antibody with the PsbA free peptide, indicating that all bands are indeed PsbA and its precursors or breakdown products. Competition assays were also performed with spinach and Chlamydomonas, confirming the identity of PsbA bands.Anti-PsbA antibodies will not detect D2 protein, as the peptide used to generate PsbA antibodies has no homology to the D2 sequence.This product can be sold containing ProClin if requested.
Lhca5 is a low abundant chlorophyll a/b-binding protein that has been found to associate with Photoystem I in sub-stoechiometric amounts. Unlike the four main Lhca-types (Lhca1-4) Lhca5 seems to be able to associate with PSI or the LHCI at varying positions. The regulation pattern for the expressino of the Lhca5 gene differs from the standard Lhc pattern as expression seems to be positively regulated under light and cold stress conditions.

Lhcb4 (CP29) is one of the 3 minor chlrorophyll a/b-binding proteins associated with Photosystem II in plants and algae. Lhcb4 has been suggested to act in the regulation of the chl a excited state concentration of PSII because of its ability of sensing lumenal pH resulting in reversible phosphorylation. In Arabidopsis thaliana 2 genes code for two isoforms Lhcb4.1 and Lhcb4.2. A third isoform (Lhcb4.3, At2g40100), probably only present in dicots, has found to be differently regulated and therefore has been denoted as Lhcb8.

Format:
Lyophilized in glycerol.
Storage Temp:
Store lyophilized/reconstituted at -20 °C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
Protein standard buffer composition: Protein standard buffer composition: Glycerol 10%, Tris Base 141 mM, Tris HCl 106 mM, LDS 2%, EDTA 0.51 mM, SERVA Blue G250 0.22 mM, Phenol Red 0.175 mM, pH 8.5, 0.1mg/ml PefaBloc protease inhibitor (Roche), 50mM DTT.
Application Details:
Positive control: a 2 μL load per well is optimal for most chemiluminescent detection systems. Standard curve: 3 loads are recommended (eg. 0.5, 2 and 4μL). For most applications a sample load of 0.2 μg of chlorophyll will give a PsaC signal in this range. Exact loads can vary with the sensitivity of your system and the abundance of the target protein in your samples. Note: Optimal quantitation is achieved using moderate sample loads/well, generally 1 to 5 ug total protein. A trial experiment may be required i) to bring your sample load within the standard curve range and ii) to obtain a signal that is strong enough to reliably quantify but not so strong as to consume ECL reagents too quickly or saturate your detection system. These goals may achieved by adjusting both sample and standard loads.
Reconstitution:
For reconstitution add 95 l of sterile water. Note that due to glycerol in buffer, the lyophilized product appears as a dense liquid rather than a powder. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently. Avoid vigorous vortexing, as buffer contains detergent. Upon reconstitution, this standard is ready-to-load and does not require any additions or heating. See additional Handling Instructions below. PsaC standard protein concentration: 0.10 pmol/ l.
Molecular Weight:
11,5 kDa (larger than native protein due to the addition of His-tag), In most gels PsaC migrates between 9 and 14 kDa

Special application note:
Handling Instructions*IMPORTANT: In our experience, viscous liquids are surprisingly stable; insufficient mixing is the most common reason for unsatisfactory results. Following mixing, briefly pulse in a microcentrifuge to collect material from cap.Standard needs to be fully thawed and thoroughly mixed before each use. Proteins tend to stratify with the more dense layer after freezing. We recommend bringing the product to room temperature and either mixing by inverting or flicking tube 5-10 times. Pipetting up and down may also provide sufficient mixing, provided the tip is moved within the tube while taking up and expelling the liquid.

Special application note:
The PsbA protein standard can be used in combination with global anti-PsbA antibodies to quantitate PsbA from a wide range of species. Global antibodies are raised against highly conserved amino acid sequences in the PsbA protein.Quantitative western blot: detailed method description, video tutorialThe goals when doing quantitative work:The sample PsbA must fall somewhere between the upper and lower standard loads. There should be at least 3 points on the standard curve.if possible, try to make the entire range of the curve around one order of magnitude or less (as in the application example).if possible, load <5 g total sample protein.1pmol of PsbA standard is a strong load for chemiluminescence, but may be appropriate for the less sensitive reagents, for example alkaline phosphatase.
The PsbA (D1) protein of Photosystem II is rapidly cycled under illumination in all oxygenic photobionts. Disruption of PsbA cycling or losses of PsbA pools are central to photoinhibition of photosynthesis in cyanobacteria, algae and plants under a wide range of conditions including excess light, low temperature and UV exposure. Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples.

Special application note:
A number of degradation products may be observed when using anti-PsbA antibodies, including products having apparent molecular weights of 24kDa and 16kDa. D1 degradation is a complex set of events and the products observed can be influenced by both the extraction procedure and the physiology of the cells prior to harvest. Third, cross-linking may occur between D1 and cytochrome b559, shifting the protein higher in the gel. In cyanobacteria (PCC7942), three different bands were competed out by preincubating the antibody with the PsbA free peptide, indicating that all bands are indeed PsbA and its precursors or breakdown products. Competition assays were also performed with spinach and Chlamydomonas, confirming the identity of PsbA bands. Anti-PsbA antibodies will not detect D2 protein, as the peptide used to generate PsbA antibodies has no homology to the D2 sequence.Example of a simulataneous western blot detection with RbcL, PsbA and PsaC antibodies.
The outer light-harvesting antenna of the photosystems (PSI and PSII) of the green unicellular alga Chlamydomonas reinhardtii is composed of pigment-binding proteins belonging to the Lhc family highly conserved in photosynthetic eukaryotes. Some of the Lhc-subtypes of Chlamydomonas share sufficient high similarity with the respective functional homologs in plants to allow specific detection with antisera generated against conserved peptide domains from plant Lhc-proteins.

The light-harvesting protein Lhca4 is one of the four main and highly conserved types of chlorophyll a/b-binding proteins (Lhca1-4) of the light harvesting antenna (LHCI) of plant photosystem I. Lhca4 is imported as a precursor from the cytosol into the chloroplast. Upon insertion into the thylakoid membrane Lhca4 forms a heterodimer (LHCI-730) with Lhca1 that associates with the PSI core close to PsaG and PsaF.A biochemical characterization of the plant LHCI antenna can be found in Klimmek et al.

Upon integration in the thylakoid membrane Lhca3 forms a heterodimer (LHCI-680) with Lhca2 that associates with the PSI core close to PsaF and PsaK.A biochemical characterization of the plant LHCI antenna can be found in Klimmek et al. (2005) The structure of the higher plant light harvesting complex I: in vivo characterization and structural interdependence of the Lhca proteins. Biochemistry 44: 3065–3073.

The major light-harvesting antenna complex II (LHCII) in photosynthetic eukaryotes is located in the thylakoid membrane of the chloroplast. It is a heterotrimeric complex formed by up to 3 different individual subtypes of chlorophyll a/b-binding proteins: Lhcb1, Lhcb2, and Lhcb3. Lhcb1 is the most abundant chlorophyll a/b-binding protein in eukaryotic phototrophs and often is coded by several nuclear genes.A molecular characterisation of the LHCII proteins can be found in Caffarri et al. (2004) A Look within LHCII: Differential Analysis of the Lhcb1−3 Complexes Building the Major Trimeric Antenna Complex of Higher-Plant Photosynthesis. Biochemistry 43 (29): 9467–9476
