Human B7H1/PD-L1 PharmaGenie ELISA Kit (SBRS0291)

PD-L1 (also called B7-H1 or CD274) is a transmembrane immune checkpoint protein that engages PD-1 on T cells to dampen anti-tumor immunity. This PharmaGenie kit from Assay Genie delivers quantitative measurement of human B7H1/PD-L1 across cell culture supernatants and blood-derived samples such as plasma and serum, supporting cancer immunotherapy research, biomarker discovery, and tumor immune evasion studies.

The 96-assay microplate is built on a quantitative immunoassay workflow with colorimetric endpoint measurement, calibrated specifically for human samples, and supplied with all reagents, standards, and protocol materials required to generate a standard curve and evaluate experimental samples. The procedure fits into typical immunology and oncology laboratory workflows studying checkpoint blockade response or pathway modulation. Detailed reagent preparation, plate layout, and storage instructions are included in the product insert accompanying the kit.
