The 13G3 monoclonal antibody specifically binds to Lymphocyte antigen 108, Ly-108. Ly-108 is a member of the signaling lymphocytic activation molecule (SLAM) family of immune receptors. Ly-108 is a type 1 transmembrane glycoprotein adhesion receptor that is expressed by T cells, NKT cells, B cells, NK cells, macrophages, dendritic cells and neutrophils. Ly-108 plays multiple roles in innate and adaptive immunity including costimulation of NK cell cytotoxicity and T cell cytokine responses. Moreover, Ly-108 has been implicated in autoimmunity.
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.
