Human PD-L1/B7-H1 XL Luminex® Performance Assay Summary
| Assay Type | bead-based multiplex assay for the Luminex® platform |
| Format | 1 x 96-well microplate and antibody-coated beads |
| Analytes Detected | Please see analyte list in assay customization tool below. |
| Performance Validation | Luminex Assays are validated for use with cell culture supernatants, plasma and serum. All Luminex assays are tested for sensitivity, intra-assay precision, inter-assay precision and to ensure assay linearity for validated sample types. Antibody pairs are selected and tested to confirm the parallel detection of natural and recombinant standard protein and to ensure the accurate determination of target analytes within biological samples. Assays for each target analyte are screened against all target analytes to confirm low antibody cross-reactivity. View Luminex High Performance Human XL validation data. |

Background: PD-L1/B7-H1
PD-L1, also known as B7-H1 and CD274, is an approximately 65 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. PD-L1 is expressed on inflammatory-activated immune cells including macrophages, T cells, and B cells, keratinocytes, enothelial and intestinal epithelial cells, as well as a variety of carcinomas and melanoma. PD-L1 binds to T cell B7-1/CD80 and PD-1. It suppresses T cell activation and proliferation and induces the apoptosis of activated T cells. It plays a role in the development of immune tolerance by promoting T cell anergy and enhancing regulatory T cell development. PD-L1 favors the development of anti-inflammatory IL-10 and IL-22 producing dendritic cells and inhibits the development of Th17 cells. In cancer, PD-L1 provides resistance to T cell mediated lysis, enhances EMT, and enhances the tumorigenic function of Th22 cells.
