Anti-VCA-2 antibodies are protein reagents that detect specific antigens. The VCA-2 antigen is another term for the human protein integrin subunit alpha 3, encoded by the ITGA3 gene. The protein is known to function in cell adhesion and cell matrix adhesion, among other biological roles. Canonically, it has an amino acid length of 1051 residues and a mass of 116.6 kilodaltons. Its subcellular localization is in the cell membrane and it is widely expressed in many tissue types. The VCA-2 protein is a member of the Integrin alpha chain protein family. Other alias names for VCA-2 include CD49C, FRP-2, and GAP-B3. Flow Cytometry, Western Blot, and Immunohistochemistry are common applications for VCA-2 antibodies.
