Used in immunological research to detect and quantify granzyme B levels in mouse samples, this ELISA kit helps study cytotoxic T-cell and natural killer (NK) cell activity. It is widely applied in inflammation, autoimmune disease, cancer immunotherapy, and viral infection studies. The assay enables researchers to assess immune response intensity by measuring granzyme B release, a key protease involved in apoptosis induction in target cells. Suitable for serum, plasma, and cell culture supernatants, it supports high-throughput screening and mechanistic studies in preclinical models.
