Used in immunological research to quantify CD3 molecule levels in pig samples, this ELISA kit enables accurate measurement of T-cell activation and immune response in veterinary and biomedical studies. It is widely applied in monitoring immune system changes during infection, vaccination, or immunotherapy in swine models. The assay supports research in infectious diseases, vaccine development, and transplantation immunology by providing a reliable tool to assess T-cell populations in porcine blood or tissue samples. Its high sensitivity and specificity make it suitable for use in preclinical studies and animal health diagnostics.
