Description: The YLI-90 monoclonal antibody reacts with the B6 mouse Ly-49I receptor. Ly49I, a member of the Ly49 family with inhibitory function, is a homodimer type II transmembrane protein and contains an Immunoreceptor Tyrosine-based Inhibitory Motif (ITIM). YLI-90 binds to subpopulations of NK, NKT and T cell lineages in the C57Bl/6 strain. This antibody does not bind to cells from BALB/c, SJL or AKR/J mice.
