Used in immunological research to quantify rat alpha interferon (IFN-α) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study immune responses, particularly in models of viral infection, autoimmune diseases, and inflammation. It is widely applied in preclinical studies to evaluate the activation of the innate immune system and to assess the efficacy of therapeutic agents that modulate interferon production. The assay provides high sensitivity and specificity, allowing accurate measurement of IFN-α concentration, which is critical for understanding disease mechanisms and immune regulation in rodent models.
