Used in immunological research to quantify rat tumor necrosis factor beta (TNF-β) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study inflammatory responses, immune system regulation, and disease mechanisms in rat models. It is particularly valuable in studies related to autoimmunity, transplantation, and cancer, where TNF-β plays a key role in cell signaling and apoptosis. The assay provides high sensitivity and specificity, allowing accurate measurement of cytokine concentrations for reliable data analysis in preclinical research.
