Human Indoleamine-2,3-Dioxygenase (IDO) ELISA Kit

Quantitative measurement of human Indoleamine-2,3-Dioxygenase (IDO) enzyme from samples including tissue homogenates and cell lysates. This research-use-only ELISA kit from Assay Genie supports investigations into tryptophan catabolism along the kynurenine pathway, a metabolic route central to tumor immunology, autoimmune disease and chronic infection research. Investigators measuring IDO expression examine its role in T-cell regulation and peripheral immune tolerance, including how IDO-mediated tryptophan depletion shapes tumor immune escape and modulates inflammatory responses. The 96-assay kit provides an in vitro tool for cell culture supernatant analysis, clinical sample screening, and basic research into immunometabolism and checkpoint biology.
