The mouse monoclonal antibody clone 29E.2A3 binds to human CD274, also known as PD-L1 or B7-H1. CD274 is a type 1 transmembrane glycoprotein and a member of the Ig superfamily. PD-L1 is a ligand for CD279 (PD-1) and plays an important role in regulating immune cell responses. This binding plays a role in clonal selection, elimination of autoreactive lymphocytes, and tolerance development. Additionally, PD-L1 can limit the activation of mature T cells. As part of the B7 ligand family, its interactions with the CD28 receptor family, including CTLA-4, are crucial for balancing T cell activation and tolerance. CD274 is expressed on activated monocytes, macrophages, dendritic cells, and T cells.
