Mouse anti Human CD49b antibody, clone 31H4 recognizes human CD49b also known as integrin alpha-2, VLA-2 subunit alpha or collogen receptor. CD49b is a 1181 amino acid ¦130 kDa single pass type-1 transmembrane glycoprotein which forms a heterodimer with integrin beta-1.

Mouse anti Human CD49b antibody, clone 31H4 has been identified as being capable of immunoprecipitating the integrin a2 subunit from human cell-lines surface labelled with 125I. It has been confirmed specific to a2 by relative expression of antigen on various cell lines by flow cytometry, and recognition of affinity purified a2b1 in dot blots.
