PD-1 Antibody

PD-1 Antibody: Cell-mediated immune responses are initiated by T lymphocytes that are themselves stimulated by cognate peptides bound to MHC molecules on antig en-presenting cells (APC). T-cell activation is generally self-limited as activated T cells express receptors such as PD-1 (also known as PDCD-1) that mediate inhibitory signals from the APC. PD-1 can bind two different but related ligands, PDL-1 and PDL-2. Upon binding to either of these ligands, signals generated by PD-1 inhibit the activation of the immune response in the absence of "danger signals" such as LPS or other molecules associated with bacteria or other pathogens. Evidence for this is seen in PD1-null mice who exhibit hyperactivated immune systems and autoimmune diseases.

• Validation:

  KO Validation (Figure 1): Anti-PD-1 antibodies (4065) specificity was further verified by PD-1 specific knockout. PD-1 signal was not detected in PD-1 knockout HeLa cells as compared to that in control wild type cells.

   

• KD validation (Figure 2): Anti-PD-1 antibody (4065) specificity was further verified by PD-1 specific knockdown. PD-1 signal in HeLa cells transfected with PD-1 siRNAs or shRNA was disrupted in comparison with that in cells transfected with control siRNAs.
