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.
This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon™ BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon™ BV605 is a tandem fluorochrome of BD Horizon™ BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon™ PE-CF594 detectors off the green or yellow-green lasers. BD Horizon™ BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.
