Used in scientific research to detect and quantify levels of the human apoptosis-related protein TFAR19 in biological samples. This ELISA kit enables researchers to study the role of TFAR19 in programmed cell death, particularly in cancer, autoimmune diseases, and neurodegenerative disorders. It is widely applied in biomedical laboratories to monitor apoptosis during drug development, evaluate cellular responses to therapeutic agents, and investigate signaling pathways involved in cell survival and death. The assay provides high sensitivity and specificity, making it suitable for analyzing protein expression changes in cell lysates and serum samples.
