Validation Data Gallery

• 

  FC experiment of human PBMCs using 65586-1-MR (same clone as 65586-1-PBS)

  1x10^6 unstimulated or PHA stimulated human PBMCs were surface stained with 0.25 ug Anti-Human PD-1 (CD279) Mouse IgG2a Recombinant Antibody (65586-1-MR, Clone: EH12.2H7) and CoraLite®488-Conjugated AffiniPure Donkey Anti-Mouse IgG(H+L). Cells were then stained with CoraLite® Plus 647 Anti-Human CD3. Cells were not fixed. This data was developed using the same antibody clone with 65586-1-PBS in a different storage buffer formulation.

  FC experiment of human PBMCs using 65586-1-MR (same clone as 65586-1-PBS)

  1x10^6 unstimulated (black) or PHA stimulated human PBMCs (red) were surface stained with 0.25 ug Anti-Human PD-1 (CD279) Mouse IgG2a Recombinant Antibody (65586-1-MR, Clone: EH12.2H7) and CoraLite®488-Conjugated AffiniPure Donkey Anti-Mouse IgG(H+L). 1x10^6 PHA treated human PBMCs were surface stained with Mouse IgG2a Isotype Control (65208-1-Ig, Clone: C1.18.4) and CoraLite®488-Conjugated AffiniPure Donkey Anti-Mouse IgG(H+L) (blue). Cells were not fixed. This data was developed using the same antibody clone with 65586-1-PBS in a different storage buffer formulation.

Background Information

Programmed cell death 1 (PD-1, also known as CD279) is an immunoinhibitory receptor that belongs to the CD28/CTLA-4 subfamily of the Ig superfamily. It is a 288 amino acid (aa) type I transmembrane protein composed of one Ig superfamily domain, a stalk, a transmembrane domain, and an intracellular domain containing an immunoreceptor tyrosine-based inhibitory motif (ITIM) as well as an immunoreceptor tyrosine-based switch motif (ITSM) (PMID: 18173375). PD-1 is expressed during thymic development and is induced in a variety of hematopoietic cells in the periphery by antigen receptor signaling and cytokines (PMID: 20636820). Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function (PMID: 19426218). It is critical for the regulation of T cell function during immunity and tolerance. Blockade of PD-1 can overcome immune resistance and also has been shown to have antitumor activity (PMID: 22658127; 23169436).
