Quinolinic Acid Analysis Service

Online Inquiry

Quinolinic acid (QUIN) is also known as 2,3-pyridinedicarboxylic acid. Quinolinic acid is one of the metabolites of tryptophan (Trp) and a selective agonist of N-methyl-D-aspartate (NMDA) receptor, which is associated with the occurrence and development of certain neuropsychiatric diseases, renal diseases, immune diseases, etc. Therefore, the determination of quinolinic acid in biological specimens is of great importance. In order to better understand the presence and dynamics of quinolinic acid in experimental animals and humans, Creative Proteomics can provide you with quinolinic acid content determination services to accelerate your project.

Targeted metabolomics is a metabolome method for detecting a certain substance or a certain type of metabolites. It has the advantages of strong specificity, high detection sensitivity and accurate quantification. We use the AB SCIEX 5500 QQQ UPLC-MS LC/MS instrument to detect the content of low abundance compounds. The absolute abundance information of the target metabolite can be obtained by comparing with the standard product.
