CD31 Antibody / PECAM-1

Flow cytometry: 1-2ug/million cells,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT

The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the PECAM-1 antibody to be titered up or down for optimal performance.

1. Staining of formalin-fixed tissues requires boiling tissue sections in 1mM EDTA, pH 7.5-8.5, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

PECAM-1, or platelet endothelial cell adhesion molecule-1, also called CD31, is made up of six extracellular immunoglobulin-like domains, a single transmembrane domain, and a cytoplasmic domain containing serine and tyrosine residues that when phosphorylated, activate the molecules signaling function. It is expressed on platelets, monocytes, neutrophils, bone marrow macrophage and dendritic cells precursors, and at the intracellular junction of endothelial cells. PECAM-1, on the endothelial lining of blood vessels, helps maintain the vascular barrier. In response to inflammatory mediators, the endothelial pull away from each other allowing fluid, inflammatory cells and proteins into the extravascular space. The inflammatory response fades as adhesion of neighboring cells increase. PECAM-1 also plays an important role in angiogenesis, promoting endothelial cell motility, junctional development and capillary morphogenesis.
