Used in immunological research to quantify rat α1-acidic glycoprotein 1 (ORM1) levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to monitor acute phase responses in rat models, particularly during inflammation, infection, or autoimmune diseases. It is widely applied in preclinical studies to assess the efficacy of anti-inflammatory drugs and to investigate the role of ORM1 in immune modulation. The assay provides high sensitivity and specificity, allowing accurate measurement of ORM1 concentration, which supports biomarker validation and disease progression tracking in experimental animal models.
