KYN / KYNA / QA ELISA pack – Standard curvesExamples of standard curves obtained with the Kynurenine, Kynurenic acid, and Quinolinic acid ELISA kits. In these competitive ELISAs, optical density is inversely correlated with Kynurenine/Kynurenic acid/Quinolinic acid levels. For illustration purposes only – do not use for calculations.
KYN, KYNA and QA along the Kynurenine PathwayKynurenine (KYN), Kynurenic acid (KYNA) and Quinolinic acid (QA) are downstream metabolites produced along the Kynurenine Pathway well-known to possess several neuromodulatory functions, as well as immuno-modulatory properties. Measurement of KYNA and QA in biological samples has been presented as possible biomarkers in several diseases.
