The AK-7 monoclonal antibody specifically binds to CD49b. CD49b is also known as integrin α2 chain, VLA-α2, and GP1a. CD49b is a type I transmembrane glycoprotein and belongs to the integrin family of extracellular matrix and cell-cell adhesion receptors. CD49b is expressed on numerous cell types including platelets, activated T cells, B cells, and monocytes. CD49b noncovalently associates with CD29 to form the VLA-2 complex (integrin α2/β1). The VLA-2 complex serves as a receptor for collagen and laminin. It can regulate responses mediated by proinflammatory effector cells.
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
