Specifications for CD273 (PD-L2) Antibody, anti-human, REAfinity™


Clone REA985 recognizes the human CD273 antigen, also known as B7-DC or PD-L2. CD273 with an approximate molecular weight of 29 kDa is a type I transmembrane protein, belonging to the B7 family of protein ligands and to the Ig superfamily. CD273 is mainly expressed on dendritic cells (DCs) and activated macrophages. It has been shown to interact with programmed-death-receptor 1 (PD-1). A stimulatory as well as a inhibitory role of CD273 in T cell activation has been proposed.
Additional information: Clone REA985 displays negligible binding to Fc receptors.
