PCNA (proliferating cell nuclear antigen) is the DNA polymerase delta auxiliary protein acting in homotrimeric form to increase the processivity of leading strand synthesis during DNA replication. PCNA is expressed in the nucleus of all proliferating cells. In response to DNA damage, it is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway. PCNA is a useful marker of DNA synthesis, as its form not involved in DNA synthesis degradates in histological preparations in the presence of organic solvents.

Cytokeratins 5, 6 and 18 are reported to be expressed in a broad range of human epithelial tissues, from simple glandular epithelia to stratified squamous epithelia. These include epithelial cells that are ectodermal, mesodermal, or endodermal in origin. These cytokeratins have been reported to be expressed in tumor cells of epithelial origin and less commonly of mesothelial origin. Non-epithelial tumors such as lymphomas do not express these cytokeratins. The recognition of cytokeratin 18 on formalin fixed paraffin embedded sections using clone LP34 may be variable.

The antibody reacts with the 4th and 5th fibronectin-like repeats of human tenascin-C. It has been demonstrated that tenascin immunoreactivity in breast carcinoma cells could be indicative of metastasis and survival. Recent studies using retrospective material showed that the expression of tenascin in invasion border of early breast cancer significantly correlates with higher risk of distant metastasis. These studies have been continued now and the preliminary results clearly suggest that expression of tenascin in invasion border of early breast cancer is significantly associated with proliferative activity and higher risk of local recurrence. This result implicates a wide application for tenascin antibodies in the breast pathology.

CD1d belongs to CD1 family of transmembrane glycoproteins, associated with beta2 microglobulin, similarly to MHC I molecules. Unlike other CD1 family members, however, CD1d can be also expressed in a non-glycosylated form, which is not associated with beta2 microglobulin. Hence it is not certain how much CD1d plays a role in the presentation of microbial lipid antigens during infection. On the other hand, it is expressed on various antigen presenting cell types. Besides it, CD1d+ thymocytes are involved in the positive selection of sublineage of NKT cells.SpecificityThe antibody MEM-65 recognizes a unique extracellular epitope of CD2, a 50 kDa glycoprotein present on the human peripheral blood T-lymphocytes and NK cells; also expressed by all thymocytes.Application detailsFlow cytometry: Recommended dilution: 4-8 ?g/ml.

The 5-HT7 Receptor Antibody was raised against synthetic peptide sequence corresponding to amino acids 8-23 of the rat 5-HT7 receptor coupled to carrier protein with glutaraldehyde. The ImmunoStar 5-HT7 receptor antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat cortex and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are 1/100 - 1/300 in PBS - biotin/avidin-HRP Technique. Note: use of Triton X-100 or other detergents is not recommended. The antibody was characterized by immunohistochemistry. Immunohistochemical staining of rat brain correlates well with Northern blot analysis, in situ hybridization and receptor autoradiography studies. Immunolabeling is completely abolished by preadsorption with synthetic rat 5-HT7 receptor (8-23). BlastP database sequence homology searches indicate that the amino acid sequence is unique to rat 5-HT7A, 5-HT7B and 5-HT7C. There is also significant sequence overlap with the mouse and human forms.
The 5-HT 2A Receptor Antibody was raised against a multiple antigenic peptide of an N-terminal synthetic sequence corresponding to amino acids 22-41 of rat 5HT2A receptor. The antibody is provided as 100 uL of affinity purified serum in PBS (0.02 M sodium phosphate with 0.15 M sodium chloride, pH 7.5) with 1% BSA (bovine serum albumin), and 0.02% sodium azide. The antiserum demonstrates strongly positive labeling of rat cortex, amygdala and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are 1/300 - 1/500 in PBS/0.03% Triton X-100 - Bn/Av-HRP Technique. The addition of intensifying reagents such as nickel ammonium sulfate to the chromogen solution will approximately double the dilution factor as recommended. Immunolabeling is completely abolished by preadsorption with synthetic rat 5HT2A receptor (22-41). Immunolabeling of Western blot revealed a single band of approximately 53kD.
Androgen Receptor (AR) is a transcriptional regulator with a broad array of functions. This marker is clinically significant in the understanding of tumour progression and tumour aggressiveness.

Background Info:
BDNF belongs to the neurotrophin family and regulates the survival and differentiation of neurons during development. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. FUNCTION: Promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. Post Translation Modification (PTM): The propeptide is N-glycosylated and glycosulfated. PTM: Converted into mature BDNF by plasmin (PLG) (By similarity). DISEASE: Defects in BDNF are a cause of congenital central hypoventilation syndrome (CCHS); also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.

CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.

Specificity:
Human proBDNF. The capture antibody used in this ELISA kit binds to an epitope within the pro-domain of proBDNF. Thus, this ELISA detects the full length form of proBDNF and does not quantify mature BDNF. Whether this ELISA kit can detect truncated BDNF is unknown at present. Mature BDNF cross-reactivity was assessed by spiking 28 kDa mature BDNF protein obtained from WHO (www.nibsc.org) into a 1/5 diluted human serum sample at 5 ng/mL, which represents a BDNF concentration level of 25 ng/mL in undiluted, normal human serum. Cross-reactivity of mature BDNF was The assay antibodies do not cross-react with nerve growth factor (NGF), neurotrophin-3 (NT-3) or NT-4/5.
Typical limit of detection (LOD) for proBDNF is 6 pg/mL determined as 150% of the blank value.
