Used in immunological research to quantify Granzyme A levels in biological samples, aiding in the study of cytotoxic T-cell and natural killer cell activity. Commonly applied in investigations of autoimmune diseases, viral infections, transplant rejection, and cancer immunology. Enables researchers to assess immune response intensity and monitor disease progression or therapeutic efficacy in experimental models. Suitable for cell culture supernatants, serum, and plasma samples. Provides a reliable, sensitive, and high-throughput method for detecting Granzyme A protein expression in mouse models.
