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.
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.
