Detection of Human VCAM‑1/CD106 by Western Blot. Western blot shows lysates of HUVEC human umbilical vein endothelial cells untreated (-) or treated (+) with 10 ng/mL Recombinant Human TNF‑ alpha (210-TA) for 24 hours. PVDF membrane was probed with 4 µg/mL of Rabbit Anti-Human VCAM‑1/CD106 Monoclonal Antibody (Catalog # MAB8092) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for VCAM‑1/CD106 at approximately 110 kDa (as indicated). GAPDH (MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.
Detection of VCAM-1/CD106 in Hut78 Human Cell Line by Flow Cytometry. Hut78 human cutaneous T cell lymphoma cell line was stained with Rabbit Anti-Human VCAM-1/CD106 Monoclonal Antibody (Catalog # MAB8092, filled histogram) or isotype control antibody (MAB1050, open histogram), followed by Phycoerythrin-conjugated Anti-Rabbit IgG Secondary Antibody (F0110). Staining was performed using our Staining Membrane-associated Proteins protocol.

VCAM-1, also known as CD106, is an immunoglobulin (Ig)-like adhesion molecule that is mainly expressed in endothelial cells and other cell types including macrophages, dendritic cells, neurons, smooth muscle cells, fibroblasts, and oocytes (1, 2). It plays a critical role in inflammation by recruiting leukocytes to acute and chronic inflammation sites (3, 4). Alternatively-spliced forms are known to occur, but the most common form is a type I transmembrane protein with a 674 aa extracellular domain (ECD) that includes seven C2-type immunoglobulin domains, a 22 aa transmembrane segment, and a 19 amino acid (aa) cytoplasmic tail. Within the ECD, human VCAM-1 shares 75% and 76% aa sequence identity with the mouse and rat VCAM-1, respectively. VCAM-1 binds to leukocyte integrins alpha 4 beta 1 (VLA-4) and alpha 4 beta 7. During the inflammatory adhesion mechanism, activated integrins halt rolling leukocytes and attach them firmly to the vascular endothelium. The VCAM-1:VLA-4/ alpha 4 beta 7 interaction is also thought to be involved in the extravasation of white blood cells through the blood vessel wall to sites of inflammation (5). ELISA techniques have shown that detectable levels of soluble VCAM-1 are present in the biological fluids of apparently normal individuals, but elevated levels of serum VCAM-1 are indicative of future Atrial Fibrillation incident as well as liver disease (6, 7). Tumor cells use overexpression of VCAM-1 as means of escaping immune surveillance (8).
