Enzyme immunoassay (ELISA) for the determination of Tryptophan in urine, serum, and plasma samples.<br><br>
After extraction and derivatization Tryptophan 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 derivatized 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.<br><br>
Quantification of unknown samples is achieved by comparing their absorbance with a standard curve prepared with known standards. For research use only, not for use in diagnostic procedures.
