The HMalpha2 antibody reacts with integrin alpha2 chain (CD49b), the 150-kDa transmembrane glycoprotein that non-covalently associates with the integrin beta1 subunit (CD29) to form the integrin alpha2beta1 complex known as VLA-2. VLA-2, a receptor for collagen and laminin, is expressed on some splenic CD4+ T lymphocytes and NK-T cells, intestinal intraepithelial and lamina propria lymphocytes, splenic NK cells, epithelial cells, and platelets, but it is not on thymocytes or Peyer’s-patch or lymphnode lymphocytes. The expression of VLA-2 is upregulated on lymphocytes in response to mitogens. The HMalpha2 antibody has been reported to partially block the interaction of T-cell blasts, but not NK cells, with collagen. Purified HMalpha2 mAb blocks the staining of splenic NK cells by the anti-CD49b/Pan-NK Cells mAb DX5 (Cat. No. 553858, for the PE conjugate). Therefore, mAb HMalpha2 may be used like the DX5 mAb for identification of NK cells. Synonyms: Integrin alpha2 chain
