A17188B_Biotin_-CD279-_Direct-ELISA_Antibody.
Direct ELISA showing biotin anti-human PD-1 (clone A17188B) bound to plate-immobilized recombinant Human PD-1 (CD279)-Fc Chimera protein (Cat. Nos. 785102, 785104, 785106 or 785108). The wells were incubated with serially diluted primary biotin antibody at room temperature for 2 hours in 1% BSA-PBS, followed by incubation with HRP Avidin (Cat. No. 405103). TMB High Sensitivity Substrate Solution (Cat. No. 421501) was used for detection. Absorbance was measured at 450 nm.

Description

Programmed cell death protein 1 (PD-1), also known as CD279, is a 55 kD member of the immunoglobulin superfamily. CD279 contains the immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic region and plays a key role in peripheral tolerance and autoimmune disease. CD279 is expressed predominantly on activated T cells, B cells, and myeloid cells. PD-L1 (B7-H1, CD274) and PD-L2 (B7-DC, CD273) are ligands of CD279 (PD-1) and are members of the B7 gene family. Evidence suggests overlapping functions for these two PD-1 ligands and their constitutive expression on some normal tissues and upregulation on activated antigen-presenting cells. Interaction of CD279 ligands results in inhibition of T cell proliferation and cytokine secretion.
