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.
The antibody was conjugated to BD Horizon™ BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40-nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.
