Human Exhausted CD8+ T Cell IHC ELISA Sampler Kit

The Assay Genie Exhausted CD8+ T Cell IHC ELISA Sampler Kit bundles 8 individual ELISA panels into a single sampler, with each panel supplied in a 48-well microplate configuration (8 x 48 assays). The sampler is purpose-built for profiling phenotypic and functional markers associated with exhausted CD8+ T lymphocytes, the hyporesponsive population that accumulates during chronic viral infection and within the tumor microenvironment. Using human-specific capture antibodies, the assays are validated for research use only on human serum and plasma, supporting immunology, immuno-oncology, and checkpoint inhibitor studies where mapping the exhaustion signature of CD8+ T cells is critical.

Each sub-kit in the bundle is supplied as a complete kit with pre-coated well plates, detection antibodies, standard diluents, wash buffer, and substrate. The sampler allows laboratories to interrogate multiple targets in parallel from the same sample cohort without committing to full single-analyte kits. Unopened kit components should be stored refrigerated, with the standard vial kept frozen at -20 degrees C and protected from light to preserve long-term stability. Researchers evaluating T cell dysfunction, CAR-T exhaustion, or response to PD-1/PD-L1 blockade frequently adopt this sampler format as a screening tool before scaling to higher-throughput panels or single-cell follow-up assays.
