Bovine CD8A (cell surface glycoprotein CD8 alpha chain) ELISA Kit (BOFI00139)

This photometric immunoassay kit from Assay Genie quantifies cell surface glycoprotein CD8 alpha chain (CD8A) in cattle-derived specimens. CD8A functions as a co-receptor on cytotoxic T lymphocytes and is widely studied in bovine immunology as a marker for monitoring cellular immunity, vaccine-induced responses, and T-cell subset dynamics in research on infectious agents such as bovine viral diarrhea virus and bovine leukemia virus. The kit is supplied as a complete set of reagents with a precoated microplate, enabling parallel processing of multiple samples per run. Reagents should be stored refrigerated upon arrival and equilibrated to room temperature before use. The assay is intended for in vitro research applications and is not validated for diagnostic procedures. Plasma or serum fractions collected from cattle are loaded into microplate wells and CD8A is captured and detected through a photometric readout proportional to analyte levels in the specimen. Researchers apply the kit to monitor changes in CD8-positive T-cell populations during experimental infection studies, characterize immune competence in dairy or beef herds, and evaluate cellular responses to candidate vaccine formulations.
