The B-K29 monoclonal antibody specifically binds to CD262 which is also known as, TNF-related apoptosis-inducing ligand receptor 2 (TRAIL Receptor 2, TRAIL-R2), Death receptor 5 (DR5), TRICK2, or KILLER. CD262 is a type I transmembrane protein that is encoded by TNFRSF10B (Tumor necrosis factor receptor superfamily, member 10b). CD262 forms a homotrimeric receptor complex that can bind homotrimeric TRAIL (CD253/APO-2 Ligand) and transduce apoptotic signals intracellularly through its cytoplasmic death domain (DD). CD262 is differentially expressed on cells from a wide variety of normal tissues and tumors. CD262 expression is upregulated by Interferon-α (IFN-α).
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.
