General description

CD31 is a single chain integral membrane glycoprotein member of the immunoglobulin superfamily of cell adhesion molecules with molecular mass of 130-140kDa. It has six Ig-like loops in the extracellular domain, a trans-membrane domain including a relatively long cytoplasmic domain. It is expressed abundantly on platelets, myeloid cells, B lymphocytes, certain T-lymphocyte cell subsets, bone marrow precursor cells, NK cells and localized to the intracellular junctions in monolayers of cultured endothelial cells.
Monoclonal Anti-CD31 (PECAM-1) is derived from the WM-59 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.

Specificity

Recognizes the CD31 (PECAM-1, endoCAM, gpIIa, hec7), human cell surface integral membrane glycoprotein. The antibody increases the rate of homotypic aggregation induced in U937 cells by TGF-β1. Its reactivity with platelets is enhanced following their washing.

Immunogen

human cell line RC-2A, originally derived from myeloid leukemia cells.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Flow cytometry/Cell sorting (1 paper)
Monoclonal Anti-CD31 (PECAM-1)-FITC antibody has been used in
  • DAB based-immunohistochemistry
  • direct immunofluorescent staining
  • fluorescence-activated cell sorting (FACS)
  • flow cytometry

Monoclonal Anti-CD31 (PECAM-1)-FITC antibody is suitable for immunostaining of HEPC-CB2 and HEPC-CB.2 cell Lines (hematopoietic cells) and flow cytometry to evaluate the percentage of contaminating endothelia cells in characterization and decidualization of endometrial stromal cells.

Biochem/physiol Actions

CD31 is also known as PECAM-1 (Platelet endothelial cell adhesion molecule-1) binds to glycosaminoglycans (GAG). Endothelial CD31 is phosphorylated on tyrosine and serine residues. CD31 is involved in some of the interactive events taking place during cardiovascular development inflammation, thrombosis, wound healing and angiogenesis.
CD31 performs in homophilic and heterophilic cell-cell adhesion and cell signalling activities. It plays a major role in the transmigration of monocytes, neutrophils and NK cells between the endothelial cell junctions into the subendothelial matrix.

Target description

Human CD31 (PECAM-1) is expressed on platelets, endothelial cells, myeloid cells, B lymphocytes, and certain T lymphocyte subsets. CD31 (PECAM-1) functions in homophilic and heterophilic cell-cell adhesion and cell signaling activities.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Preparation Note
