Description
The Mouse IDO1 Inhibitor Screening Assay Kit is designed to measure inhibition of the murine IDO1 enzyme. This kit is simple to use. Inhibitor and enzyme are added to a sample containing L-Trp substrate. After a room temperature incubation, activity is determined by measuring the absorption of reaction product at l=320-325 nm.

Background
L-tryptophan (L-Trp) is an essential amino acid necessary for protein
synthesis in mammalian cells and the L-Trp to kynurenine (Kyn) pathway is firmly established as
a key regulator of innate and adaptive immunity. Catabolism of L-Trp to Kyn maintains an
immunosuppressive microenvironment by starving immune cells of L-Trp and releasing
degradation products of L-Trp that have immunosuppressive functions. Indoleamine 2,3-
dioxygenases (IDO1 & IDO2), two of the rate limiting enzymes in this pathway, are upregulated
in many tumors, providing cancer cells with an avenue for immune evasion.
