VCAM-1 HUMAN

General description

Vascular cell adhesion molecule 1 (VCAM-1) is a 110kDa cell surface integral membrane glycoprotein that belongs to the Ig (immunoglobulin)-related superfamily of adhesion molecules. The human VCAM-1 gene codes for a 715 amino acid transmembrane glycoprotein containing a 19 amino acid cytoplasmic domain, a 22 amino acid transmembrane domain, and a 674 amino acid extracellular domain. It is expressed on endothelial cells. Recombinant human VCAM-1 is a 110kDa glycoprotein comprising the extracellular domain (673 amino acid residues) of VCAM-1. Monomeric glycosylated VCAM-1 migrates at an apparent molecular weight of approximately 74.1kDa by SDS-PAGE analysis under reducing conditions.

Biochem/physiol Actions

The primary function of VCAM-1 is the mediation of leukocyte-endothelial cell adhesion and signal transduction. VCAM-1 may play a vital role in the development of several diseases, including atherosclerosis and rheumatoid arthritis. The protein has a crucial role in early embryonic development. It also has a role in lymphocyte trafficking and homeostasis of lymphocyte development.

Physical form

Lyophilized from 10 mM Sodium Phosphate, pH 7.0.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
