Determination of L-Kynurenine levels in cell cultures through microdialysis collection and by ELISA quantification
Murine CT26 colorectal cancer cell line WT or stably transfected with vector containing cDNA encoding for indoleamine 2,3 dioxygenase (IDO1) or Human U-87 MG glioblastoma cell line were cultured for 48 hours. Cell culture was subjected to microdialysis collection (3 fractions collected) and kynurenine was measured using the Kynurenine ELISA kit (BA-E-2200). As expected, kynurenine level was higher in IDO1-proficient CT26 cells than in parental (WT) CT26 cell lines, and also high in U87-MG cells.

The L-Kynurenine ELISA is an easy-to-use assay tailored for the quantification of Kynurenine across large series of samples. Optimized for the analysis of biological fluids (plasma, cell culture supernatant, serum...), the KYN ELISA features a lower limit of detection at 45.7 ng/ml and a minimal sample volume of 20µl, thus allowing longitudinal studies in mice.
