Kynurenic acid ELISA test in serum (KYNA)

Kynurenic acid ELISA test in serum (KYNA)
Kynurenic acid (KYNA) is a metabolite of tryptophan formed enzymatically along the kynurenine pathway. The first step in the pathway is catalyzed by tryptophan 2, 3-dioxygenase (TDO) and indoleamine 2, 3-dioxygenase (IDO), enzymes responsible for tryptophan degradation to formylkynurenine.
