The CNX46-3 monoclonal antibody specifically binds to mouse CD160, also known as Natural Killer Cell Receptor BY55. CD160 is a glycosyolphosphatidylinositol-anchored membrane glycoprotein that contains a single Ig domain. This member of the Ig Superfamily was the first identified as a MHC Class I antigen-specific Ig-like Receptor that was expressed by mouse NK cells. As a receptor, CD160 can bind to classical and non-classical MHC class I molecules with low affinity. As a ligand, CD160 can bind to HVEM (Herpes Virus Entry Mediator, a TNF Receptor Family Member). CD160 is expressed on a subset of NK cells, NKT cells, activated CD8+ T cells and TCR γδ T cells. The functions of CD160 have been reported to regulate NK cell activation both positively and negatively, depending on stimulus.
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.
