Used in biomedical research to quantify levels of SERPINB9, a protein involved in regulating cell death and immune response. Helps study its role in diseases like cancer, autoimmune disorders, and viral infections. Enables researchers to measure SERPINB9 concentration in biological samples such as serum, plasma, and tissue lysates. Supports investigation into immune cell function, particularly in cytotoxic T cells and natural killer cells. Useful in inflammation and apoptosis studies. Provides a reliable tool for monitoring disease progression and evaluating therapeutic interventions in experimental models.
