Used to measure indoleamine 2,3-dioxygenase (IDO) activity in mouse samples, this ELISA kit is essential in immunology and cancer research. It enables researchers to quantify IDO levels in cell lysates or tissue homogenates, helping assess immune modulation in tumor microenvironments, autoimmune diseases, and inflammatory conditions. The kit supports drug development studies targeting IDO pathways, particularly in immunotherapy, where IDO inhibition can enhance anti-tumor immune responses. Its high sensitivity and specificity make it suitable for preclinical studies involving mouse models of disease.
