Anti-CD31/PECAM-1 Antibody

Studying vascular endothelium, leukocyte transmigration, or angiogenesis often hinges on reliable detection of the 130 kDa transmembrane glycoprotein CD31 (PECAM-1). This unconjugated Mouse monoclonal reagent, supplied by Antibodies.com, recognizes the human target and is validated for Western blot analysis of cell and tissue lysates.

Each 100 µl vial contains purified immunoglobulin in PBS (pH 7.4) supplemented with 0.1 mg/ml BSA, 0.02% sodium azide as preservative, and 50% glycerol as cryoprotectant, supporting standard immunoblotting workflows. CD31 is a well-characterized marker of endothelial cells and platelets, and antibodies against PECAM-1 are routinely used to confirm vascular identity, monitor angiogenic processes, and characterize tumor microvasculature in cardiovascular and oncology research.

For short-term use, keep the antibody refrigerated; for extended storage, aliquot and freeze at -20°C to limit repeated freeze-thaw cycles and preserve binding activity. Researchers working with human samples who need a monoclonal primary antibody for WB will find this reagent a focused tool for interrogating PECAM-1 expression.
