Used in research settings to quantitatively measure human insulin receptor β (ISR-β) levels in biological samples such as cell lysates, serum, or plasma. This ELISA kit enables scientists to study insulin signaling pathways, evaluate insulin resistance mechanisms, and investigate metabolic disorders like type 2 diabetes. It is also applied in drug development and preclinical studies to assess the impact of therapeutic compounds on insulin receptor expression and activity. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of ISR-β in small sample volumes.
