Quinolinic acid ELISA kits are designed for the specific detection of quinolinic acid in biological samples. Quinolinic acid is a compound that is metabolized in humans and can be detected in CSF, urine, fecal, and serum samples. It has the chemical formula C7H5NO4 and belongs to the pyridinecarboxylic acids class of molecules. Quinolinic acid serves as the the biosynthetic precursor to nicotine in plants. It is also a downstream product of the kynurenine pathway, which metabolizes the amino acid tryptophan. It has been reported to act as an NMDA receptor agonist with a possible role in neurodegenerative disorders.
