Kynurenic Acid ELISA kit
Ref: IS-I-0200R
Cross-validation of Kynurenic Acid ELISA and LC/MS data in human serum samples
Human serum samples (n=40) were processed for Kynurenic Acid measurement by mean of both KYNA ELISA kit and liquid chromatography–mass spectrometry (LC/MS). As depicted, results obtained with ELISA and LC/MS are highly correlated (R Squared=0,9902).
Kynurenic acid (KYNA) is a downstream metabolite produced along the Kynurenine Pathway well-known to possess several neuromodulatory functions, as well as immuno-modulatory properties. Measurement of KYNA in biological samples has been presented as a possible biomarker in several diseases including neurological or psychiatric disorders.
The Kynurenic Acid ELISA kit is optimized for the quantitation of Kynurenic Acid (KYNA) within serum samples. This easy-to-use competitive assay is well-suited for both small and large series of samples. Working with a 50µL sample volume, this assay enables pre-clinical and clinical sample testings.
