Anti-CD31 Antibody

This polyclonal reagent from Antibodies.com targets CD31, also known as PECAM-1, a transmembrane glycoprotein that is widely used as a marker for vascular endothelial cells, platelets, and selected leukocyte populations. Raised in rabbit and supplied unconjugated at 100 µl, the antibody is validated for western blot, immunohistochemistry, immunofluorescence, and ELISA workflows using human and mouse samples. Investigators commonly apply it to studies of angiogenesis, vascular development, tumor microvasculature, and endothelial barrier function across tissue sections and cell-based assays. Refrigerated storage is recommended to preserve activity over repeated freeze-thaw cycles for the liquid-format vial.
