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

This quantitative immunoassay from Assay Genie enables measurement of indoleamine-2,3-dioxygenase (IDO) protein levels in rat samples using an absorbance-based read-out. The kit contains reagents for 96 individual assays and is configured for research use only, supporting studies in inflammation, immune regulation, and tumor microenvironment biology.

IDO catalyzes the first rate-limiting step in tryptophan catabolism along the kynurenine pathway and has been investigated for its role in immune tolerance, tumor immune escape, and host-pathogen interactions. The assay accepts plasma specimens, serum samples, and tissue homogenate preparations derived from rat models. Each kit supplies all components needed to produce a quantitative standard curve, including a pre-coated microplate, protein standard, detection reagents, wash buffer, and substrate. The procedure is intended for in vitro laboratory research, with absorbance read-outs interpreted against the generated standard curve to determine IDO concentration in each experimental specimen.
