Description

Immunogen

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

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.

Antigen Background

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.

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.
5th Workshop: code No. P025

Preparation Note

Prepared by conjugation to fluorescein isothiocyanate isomer I (FITC). This green dye is efficiently excited at 495 nm and emits at 525 nm.

Application

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 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.
