Mouse B7-DC

The TY25 monoclonal antibody specifically binds to CD273, also known as B7-DC or PD-L2. CD273 is a 42-kDa type I membrane glycoprotein encoded by the Pdcd1lg2 gene of the B7 family of the Ig superfamily. Pdcd1lg2 mRNA is expressed selectively in dendritic cells (DC), liver, and a few transformed cell lines (hepatic, neuroblastoma, and myeloid), but not in lymphoid tissues or macrophages. The protein has not been detected on resting peripheral T and B lymphocytes, macrophages, or DC, but it is upregulated upon activation of T cells, macrophages, and DC by a variety of stimulatory factors. B7-DC's receptor, PD-1, contains an ITIM (Immunoreceptor Tyrosine-based Inhibitory Motif) on its intracytoplasmic region and is expressed on activated B and T lymphocytes, suggesting that B7-DC-PD-1 interaction may be involved in the negative regulation of immune responses. The second PD-1 ligand, B7-H1 (PD-L1), is also a member of the B7 family of the Ig superfamily.  B7-DC may also participate in positive immunoregulation, or costimulation of T cells, through an additional receptor, which is not PD-1 and distinct from the alternate receptor for B7-H1. Moreover, B7-DC is the first B7 ligand that has been found to participate in bi-directional communication; ligation of B7-DC on DC stimulates those DC. The TY25 antibody blocks the binding of B7-DC to PD-1, but not to its alternate ligand. The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 786-nm.  BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
