Used in biomedical research to quantify levels of FAS/CD95, a key cell surface receptor involved in apoptosis, in mouse samples. This ELISA kit enables researchers to study programmed cell death pathways in immune regulation, cancer development, and autoimmune diseases. It is commonly applied in studies involving tissue injury, neurodegenerative disorders, and drug-induced cytotoxicity in mouse models. The assay provides a sensitive and specific method to measure soluble or membrane-bound FAS protein in serum, plasma, or cell culture supernatants, supporting investigations into therapeutic interventions that modulate apoptotic signaling.
