Used in immunological research to quantify indoleamine 2,3-dioxygenase (IDO) levels in mouse samples. This kit enables researchers to study IDO expression in immune cells, tumors, and tissues, helping to investigate its role in immune regulation, cancer progression, autoimmune diseases, and pregnancy. Commonly applied in studies involving immunosuppression, where IDO activity influences T-cell responses and tolerance. Provides a reliable method for measuring IDO in cell lysates, serum, and tissue homogenates during preclinical studies.
