Human TDO Inhibitor Screening Assay Kit (384)

Cat.No.: Kit-1762
Product Overview: 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. Tryptophan 2,3 dioxygenase (TDO) is upregulated in many tumors, providing cancer cells with an avenue for immune evasion.
Size: 384 reactions
Description: The TDO Inhibitor Screening Assay Kit is designed to measure TDO enzyme inhibition. The TDO Inhibitor Screening Assay Kit is simple to use. Inhibitor and enzyme are added to a sample containing L-Trp substrate. After a room temperature incubation, activity is measured by measuring the absorption of reaction product at  = 320-325 nm.
Applications: Useful for the study of TDO enzymology, screening inhibitors and selectivity profiling.
Storage: Stable at least 6 months from date of receipt, when stored as directed. Kit components require different storage conditions. Be sure to store each component at the proper temperature upon arrival.
Kit Components: TDO His-Tag: 100 µg; -80°C TDO Reaction Solution: 4 x 10 ml; -80°C TDO Assay Buffer: 2 x 1 ml; -80°C UV transparent 384-well plate: 1; Room Temp.
