BD OptiBuild™ BV605 Mouse Anti-Human CD140b

Reacts with platelet derived growth factor (PDGF) receptor β, a 170-190 kDa single transmembrane glycoprotein expressed on fibroblasts, smooth muscle cells, glial cells and chondrocytes. PDGF receptors, α and β, are single glycoproteins  with intracellular tyrosine kinase domains. They are structurally similar to M-CSF receptor and CD117 (c-kit). Their ligand, PDGF, is a mitogen for connective tissue cells and glial cells. PDGF plays a role in wound healing and acts as a chemoattractant for fibroblasts, smooth muscle cells, glial cells, monocytes and neutrophils. Functional PDGF is secreted as a disulfide-linked dimer of A and B chains (PDGF-AA, PDGF-BB or PDGF-AB). Binding of divalent PDGF induces receptor dimerization with three possible forms: αα, αβ, ββ. The PDGF receptor α-subunit binds both PDGF A and B chains, whereas the receptor β-subunit binds only PDGF B chain. Both receptor subunits can stimulate mitogenic responses, only the β subunit can induce chemotaxis. 28D4 is specific for PDGFRβ and does not cross-react with PDGFRα.

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.
