Used in apoptosis research to quantify BAX protein levels in cell lysates or tissue samples. Enables scientists to study programmed cell death mechanisms in diseases like cancer, neurodegenerative disorders, and ischemic injuries. Commonly applied in drug development to assess compound effects on mitochondrial apoptosis pathways. Supports biomarker validation by measuring BAX activation in response to therapeutic agents. Suitable for high-throughput screening in preclinical studies.
