CD49b Hamster anti-Mouse, Brilliant Violet 711, Clone: HMα2, BD Optibuild™

Description

The HM α 2 antibody reacts with integrin α 2 chain (CD49b), the 150-kDa transmembrane glycoprotein that non-covalently associates with the integrin β 1 subunit (CD29) to form the integrin α 2β 1 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 HM α 2 antibody has been reported to partially block the interaction of T-cell blasts, but not NK cells, with collagen. Purified HM α

The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm. BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor™ 700-like dyes (eg, 712/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor™ 700 and PerCP-Cy5.5 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
