Isotype:  Murine IgG1k

Immunogen: Recombinant human CD279

INFORMATION: Human CD279 (PD-1, Programmed death 1) is a 55 kd Ig superfamily member  with sililarity to CD28 and CD152(CTLA-4).    It is expressed on activated T and B and myeloid cells, and engagement by its ligands PD-L1 (CD274, B7-H1) or PD-L2 (B7-DC) can inhibit proliferation and cytokine expression.  In mice blockade of PD-1 ligand interaction has been used to augment T cell anti cancer responses (3,4,5).

Anti-CD279 antibody clone ANC4H6 binds to CD279 present on PHA activated PBMC in FACS, and binds to recombinant CD279 in EIA.  Pre incubation of recombinant CD279-coated plates with ANC4H6 blocks binding of biotinylated recombinant CD273  in EIA.
