DatasheetMSDSProtocol
Quinolinic acid (QA) is a metabolite produced along the Kynurenine Pathway, which converts the aminoacid Tryptophan to NAD+, a co-factor of many enzymatic reactions.
The Quinolinic Acid ELISA kit is optimized for the quantitation of Quinolinic Acid (QUIN or QA) within serum and plasma samples. This easy-to-use competitive assay is well-suited for both small and large series of samples. Working with a low sample volume of 25µL, this assay enables pre-clinical and clinical sample testings.
