Human Programmed Cell Death Protein 1 Ligand 1 (PDCD1LG1) ELISA Kit

For immunology and oncology laboratories studying the PD-1/PD-L1 immune checkpoint axis, this ELISA Kit from Assay Genie provides quantitative measurement of human PD-L1, the ligand encoded by the PDCD1LG1 gene. The assay supports investigation of how PD-L1 expression contributes to immune evasion within tumor microenvironments and how its levels shift in response to checkpoint inhibitor treatment.

Validated for tissue homogenates, cell lysates, and cell culture supernatants, the kit serves in vitro cell-based assays, ex vivo tissue analyses, and routine cell biology workflows. Each kit supplies reagents for 96 individual assays in a microplate layout, paired with an absorbance-based readout compatible with standard laboratory plate readers. Components are intended for refrigerated storage prior to first use, and the package includes a step-by-step protocol, reference standard, and detection antibody for straightforward bench implementation. Reactive with human samples and labeled for research use only, this assay serves applications spanning cancer immunotherapy development, autoimmune disease modeling, and infectious disease research where PD-L1 quantification informs experimental conclusions.
