Background

Cluster of differentiation (CD31), Platelet Endothelial Cell Adhesion Molecule 1 (PECAM-1), is a 30kDa type I transmembrane glycoprotein expressed by endothelial cells, platelets, leukocytes and some lymphocytes (e.g., B and T-cell subsets). Structurally, PECAM-1 consists of six extracellular immunoglobulin-like domains which serve to support various functions including homophilic binding, maintaining high expression of PECAM-1 within endothelial intercellular junctions, and supporting endothelial cell migration (1,2). PECAM's homophilic binding underscores its role in vascular barrier integrity and leukocyte trans-endothelial movement. However, PECAM may also engage in heterophilic interactions with molecules such as glycosaminoglycans (GAG), integrin alpha 5 beta 3, CD38 in lymphocytes and CD177/PR3 in neutrophils (2).

PECAM's intracellular cytoplasmic domain consists of a sequence of 118 amino acids and contains serine and tyrosine (also referred to as immunoreceptor tyrosine-based inhibitory motifs-ITIMs) residues, which may be phosphorylated upon cellular stimulation (3). ITIMs are phosphorylated by Src-family kinases and non-Src family kinases (e.g., Csk), leading to a conformational change which supports interactions with Src homology 2 (SH2) domain containing proteins such as protein-tyrosine phosphatase, SHP-2 (1,2). Formation of SHP-2/PECAM-1 complexes induces endothelial cell migration through the dephosphorylation of focal adhesion kinase and regulation of RhoA activity (1). Signaling downstream of ITIM tyrosine phosphorylations also plays a role in PECAM's anti-apoptotic activity, a function which is independent of its interaction with SHP-2. In platelets and leukocytes, phosphorylation of PECAM's cytosolic domain is inhibitory, preventing their activation.

FAQs for CD31/PECAM-1 Antibody (NB100-2284). (Showing 1 - 3 of 3 FAQs).

  1. I'm interested in your antibody CD31/PECAM1 ref: NB100-2284. I'd like to stain human endothelial cells injected in mouse muscle. Do you know if your antibody cross-reacts with mouse? Is this antibody working on Immunohistochemistry frozen sections?
    • NB100-2284 reacts with human and mouse in WB, immunocytochemistry and IHC on both frozen and paraffin-embedded tissues. Novus also offers sample sizes of several products, which may be identified by a SS at the end of the catalog number (ie. NB100-105SS is the sample size of NB100-105). We also offer Super Novus packs to many common antigens. These kits enable customers to test several different antibodies to the target at a discounted rate.
  2. I'm interested in your antibody CD31/PECAM1 ref: NB100-2284. I'd like to stain human endothelial cells injected in mouse muscle. Do you know if your antibody cross-reacts with mouse? Is this antibody working on Immunohistochemistry frozen sections?
    • As is listed on our datasheet, NB100-2284 reacts with human and mouse in WB, immunocytochemistry and IHC on both frozen and paraffin-embedded tissues. Novus also offers sample sizes of several products, which may be identified by a "SS" at the end of the catalog number (ie. NB100-105SS is the sample size of NB100-105). We also offer Super Novus packs to many common antigens. These kits enable customers to test several different antibodies to the target at a discounted rate.
  3. I am looking for references concerning the use of NBP2-15797, NBP1-47913 and NB100-2284 in IHC on PFA- fixed section.
    • Among your mentioned catalog numbers (NBP2-15797, NBP1-47913 and NB100-2284), we have published references for NB100-2284 only. Hylander et al. 2013 (Journal of Translational Medicine 2013, 11:110) have cited the IHC-P use of NB100-2284 and this paper has also explained a nice detailed IHC-P protocol that you may follow if you want to. NBP1-71663 is our bestselling catalog number among all CD31/PECAM1 antibodies and it has been cited in two publications, both explaining its use in IHC-P assays (Pratheeshkumar et al. 2012 PLoS One. 2012;7(10):e47516; and Pratheeshkumar et al. 2012 PLoS One. 2012;7(12):e52279)
