Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) serves as an important control element in the regulation of photosynthetic carbon metabolism in C4 and CAM plants. This is the first enzyme of the pathway, and PEPC enzymes are encoded by a small multigenic family. Several isoforms of PEPC have been characterised in maize, sorghum and sugarcane. These isoforms are involved in several functions such as the initial fixation of atmospheric CO2 (= C4 PEPC) and anaplerotic functions associated with nitrogen assimilation or amino acid biosynthesis (Lepiniec et al. 1994).

Product Type:
Antibody
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

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.
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.This is a recombinant protein standard, source: Synechocystis PCC 6803.

The PsbA protein standard can be used in combination with global anti-PsbA antibodies to quantitate PsbA from a wide range of species.

The pmoles in the standard refer to pmoles of rbcL monomers.Why can I not see the standard band using Coomasie stain? The reason that you do not see Rubisco standard on a gel is, that you have probably used it in concentration which is recommended for western blot detection, and it is too low to allow to see this protein using Coomasie stain. In such a case, you should load more Rubisco standard on a gel and stain it with more sensitive Coomasie stain or with silver. You can not use such a gel for western blot, as using higher concentration of this standard will not work for quantitation using western blot technique.
