Human Cluster Of Differentiation 8a (CD8a) ELISA Kit

Quantitative measurement of human CD8a is supported by this enzyme-linked immunosorbent assay kit from Assay Genie, formatted to run 96 assays per box. CD8a, also known as cluster of differentiation 8a, is a transmembrane glycoprotein expressed predominantly on cytotoxic T lymphocytes. It functions as a co-receptor that pairs with the T-cell receptor during recognition of peptide antigens bound to MHC class I molecules, making it a central marker in studies of cellular immunity.

Researchers investigating T-cell development, tumor-infiltrating lymphocytes, viral immune responses, and checkpoint inhibitor biology can use this kit to quantify CD8a across multiple sample types, including tissue homogenates, cell lysates, and cell culture supernatants. The procedure is read colorimetrically on a standard microplate reader, and the reagents are intended for research use only. Each kit provides plates, buffers, and standards for a complete workflow from sample preparation through final quantification.
