IDO1 Cellular Activity QuickDetect™ Supplements

Catalog #: 62000-1
Size: 100 reactions
L-Trp is an essential amino acid necessary for protein synthesis in mammalian cells, and the L-Trp to 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 LTrp that have immunosuppressive functions. IDO1 is upregulated in many tumors, providing cancer cells with an avenue for immune evasion.
The IDO1 Cellular Activity QuickDetectTM Supplements are designed to complement the hIDO1-HEK293 Recombinant Cell Line (BPS Cat. #60532) or other IDO1- expressing cell lines. This kit contains the cell culture medium supplements necessary for activation of IDO1 and for the analysis and detection of Idoleamine 2,3 dioxygenase 1 (IDO1)- catalyzed conversion of L-tryptophan (L-Trp) to Kynurenine (Kyn). The supplements and the detection reagents, when used as described, allow for indirect measurement of Kyn levels by analyzing absorption at 480 nm.
Materials Required But Not Provided:

hIDO1-HEK293 Recombinant Cell Line (BPS Cat. #60532) or other IDO1-expressing cell line and appropriate cell culture medium
INCB024360 (BPS Cat. #27339) or other IDO1 inhibitor
6.1 N (concentrated) trichloroacetic acid*
17.4 N (concentrated) glacial acetic acid*
*Note: both trichloroacetic acid and acetic acid are strongly corrosive acids; please use gloves and appropriate protective clothing.

Indoleamine 2,3-dioxygenase 1, IDO

Instructions for use:
see data sheet for detailed culturing and assay protocol.
Storage / Stability:
Stable for at least 6 months when stored as directed
Monitor IDO1 pathway activity. Screen for activators or inhibitors of IDO1 in a cellular context
