Used in immunological research to quantify human Type I interferon receptor 2 (IFNAR2) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the expression and regulation of IFNAR2 in the context of viral infections, autoimmune diseases, and cancer immunotherapy. It supports investigation into interferon signaling pathways, helping assess receptor dynamics during immune responses and therapeutic interventions. The assay is suitable for monitoring changes in IFNAR2 associated with disease progression or treatment effects in clinical and preclinical studies.
