Used in biomedical research to quantify levels of apoptosis inhibitors in cell or tissue samples. Helps study the regulation of programmed cell death, which is critical in cancer research, neurodegenerative diseases, and autoimmune disorders. Enables researchers to evaluate how therapeutic agents affect apoptosis pathways by measuring changes in inhibitor of apoptosis proteins (IAPs). Commonly applied in drug development and molecular biology labs to assess cellular responses to treatments such as chemotherapy or radiation. Provides a reliable, sensitive method for detecting IAPs in human serum, plasma, or cell lysates, supporting studies on disease mechanisms and potential biomarkers.
