A suggested positive control is Raji cell lysate. PA5-20343 can be used with blocking peptide PEP-0463. The PA5-20343 immunogen is located within amino acids 60 - 110 of PD-L1. Predicted molecular ~ 33 kDa. In Western blot applications, this antibody has been observed to detect a band at: 37 kDa Predicted species reactivity based on immunogen sequence: Rat: (77%), Mouse: (71%)

Cell-mediated immune responses are initiated by T lymphocytes that are themselves stimulated by cognate peptides bound to MHC molecules on antigen-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. PDL-1 is a B7-related protein that inhibits cell-mediated immune responses by reducing the secretion of IL-2 and IL-10 from memory T cells. This suggests that PDL-1 may be useful in reducing allogenic CD4+ memory T-cell responses to endothelial cells, thereby reducing the likelihood of host immune responses to allografts. At least two isoforms of PDL-1 are known to exist; this antibody is specific to the larger isoform. PDL-1 antibody has no cross-reactivity to PDL-2.
