Enzyme Immunoassay (ELISA) for the determination of L-Kynurenine in serum, EDTA plasma samples and various biological samples for the determination of kynurenine homeostasis. After acylation Kynurenine is quantitively determined by ELISA. The competitive ELISA uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The acylated standards, controls and samples and the solid phase bound analyte compete for a fixed number of antibody binding sites. When the system is in equilibrium, free antigen and free antigen-antibody complexes are removed by washing. The antibody bound to the solid phase is detected by an anti-rabbit IgG-peroxidase conjugate using TMB as a substrate. The reaction is monitored at 450nm. Quantification of unknown samples is achieved by comparing their absorbance with a reference curve prepared with known standards.
