Used in biological research to quantify FAS ligand (FASL) levels in mouse samples, this ELISA kit enables the study of apoptosis mechanisms in immune regulation and inflammatory diseases. It is widely applied in investigating autoimmune disorders, cancer progression, and transplant rejection by measuring FASL expression in serum, plasma, or cell culture supernatants. The assay supports high-throughput analysis with high sensitivity and specificity, making it valuable in preclinical studies and drug development targeting the FAS/FASL pathway.
