The IIA1 monoclonal antibody specifically recognizes CD49e, a type I transmembrane glycoprotein which is also known as Integrin α5 Chain or VLA-5 α chain (VLA-5α). Following translation, CD49e is cleaved into two disulfide-linked chains of 135 and 25 kDa that associate with β1 integrin (CD29) to form the VLA-5 (Integrin α5/β1) complex. The VLA-5 complex is a well-established fibronectin receptor that is expressed on many cell types, including fibroblasts, endothelial cells, epithelial cells, platelets, thymocytes, T cells, B cells, the myeloid cell line U937, K562 and some melanoma cell lines. This clone inhibits α5β1 binding of ligands. It is useful for studies of the expression and function of this integrin.
The antibody was conjugated to BD Horizon™ BV480 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 436-nm and Em Max at 478-nm, BD Horizon™ BV480 can be excited by the violet laser and detected in the BD Horizon™ BV510 (525/40-nm) filter set. BV480 has less spillover into the BV605 detector and, in general, is brighter than BV510.
