Human T-cell surface glycoprotein CD8 alpha chain (CD8A) ELISA Kit

This quantitative immunoassay from Assay Genie enables researchers to measure the alpha chain of the CD8 co-receptor in human research samples. CD8A is expressed primarily on cytotoxic T lymphocytes and certain NK cell populations, where it stabilizes T-cell receptor engagement with MHC class I molecules during antigen recognition. Quantifying circulating CD8A supports studies of immune activation, viral infection responses, transplant monitoring, and T-cell development in immunology research.

The kit is supplied as a complete package containing pre-coated plate strips, detection antibody, recombinant standard, assay buffers, and substrate solution in individual vials. Researchers should store unused components refrigerated and protect reagents from light to preserve reagent activity across the shelf life of the product. The plate-format assay is configured for ninety-six reactions and is intended for research use only, not for clinical diagnostic applications.

Recommended sample matrices include human serum or plasma prepared using standard collection and processing protocols. Researchers working with cell culture supernatants may evaluate compatibility empirically, though validation for those sample types is the user's responsibility. The assay delivers a quantitative absorbance-based readout that supports comparison of CD8A levels across experimental groups in immunological research.
