tcue433 ELISA Kit for 5-Hydroxyindoleacetic Acid (5-HIAA)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to 5-Hydroxyindoleacetic Acid (5-HIAA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled 5-Hydroxyindoleacetic Acid (5-HIAA) and unlabeled 5-Hydroxyindoleacetic Acid (5-HIAA) (Standards or samples) with the pre-coated antibody specific to 5-Hydroxyindoleacetic Acid (5-HIAA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of 5-Hydroxyindoleacetic Acid (5-HIAA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of 5-Hydroxyindoleacetic Acid (5-HIAA) in the sample.
