Used in immunological research to quantify human anti-lymphocyte globulin (ALG) levels in biological samples. This ELISA kit enables detection and measurement of antibodies targeting lymphocytes, which is critical in studying immune responses in organ transplantation, autoimmune diseases, and immunosuppressive therapies. It supports monitoring of ALG concentration in patient sera to assess treatment efficacy and immune system modulation. Widely applied in clinical research and pharmaceutical development for evaluating immunotherapies and anti-rejection drug regimens.
