Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the extracellular domain of human CD58 protein. Background CD58, also known as lymphocyte function-associated antigen 3 (LFA-3), is a ubiquitously expressed glycoprotein anchored to the plasma membrane through a transmembrane domain or a GPI linkage (1). Research studies have demonstrated that CD58 plays a critical role in immune synapse formation by functioning as a co-stimulatory adhesion molecule upon engagement of the CD2 antigen on the surface of T cells and NK cells. As such, the CD58-CD2 axis facilitates the execution of immune effector cell functions, including activation, proliferation, and cytotoxicity (2-4). In the context of cancer, recent studies have pointed to the CD58-CD2 axis as a stimulatory immune checkpoint, and lesions to this axis compromise anti-tumor immune responses (5,6).
