Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.
VCAM-1 Antibody recognizes endogenous levels of total VCAM-1 protein. This antibody cross-reacts with proteins of unknown origin 48 and 49 kDa.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro354 of human VCAM-1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
VCAM-1 (vascular cell adhesion molecule-1) is a transmembrane glycoprotein containing multiple amino-terminal extracellular Ig-like domains, a transmembrane domain, and a short carboxy-terminal cytoplasmic domain (1). Alternative splicing generates two isoforms of VCAM-1 (2). The role of VCAM-1 during infection and inflammatory diseases is well characterized. Expression of VCAM-1 is induced in endothelial cells by inflammatory cytokines including TNF-α and IL-1β (1). VCAM-1 on endothelial cells interacts with the integrin VLA-4 (α4β1) on leukocytes to mediate migration of circulating leukocytes from the blood across the endothelium and into tissues (3).
