    Direct ELISA showing purified anti-human PD-1 (clone A17188B) bound to plate-immobilized recombinant human PD-1 (CD279)-Fc Chimera protein (Cat. Nos. 785102, 785104, 785106, and 785108). The wells were incubated with serially diluted primary antibody at room temperature for 2 hours in 1% BSA-PBS, followed by incubation with HRP goat anti-mouse IgG (Cat. No. 405306). 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.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. For Direct ELISA, the optimal concentration of this reagent for the specific application and the experiment design should be established by the end-user. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

A17188B antibody can block the binding of NAT105 and EH12.2H7 antibodies to the target.
