The 5-HIAA (5-Hydroxyindoleacetic Acid) ELISA Kit is specifically designed for the accurate and precise detection of 5-HIAA levels in various biological samples including urine, plasma, and cerebrospinal fluid. This kit offers high sensitivity and specificity, ensuring reliable and reproducible results for a wide range of research applications.5-HIAA is a metabolite of serotonin and is commonly used as a biomarker for various neurological and psychiatric disorders, including carcinoid tumors and serotonin syndrome.
Monitoring 5-HIAA levels can provide valuable insights into the serotonin pathway and help in the diagnosis and treatment of these conditions.With its easy-to-use protocol and excellent performance characteristics, the 5-HIAA ELISA Kit is a valuable tool for researchers and healthcare professionals studying serotonin metabolism and related disorders.
This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with 5-HIAA. During the reaction, 5-HIAA in the sample or standard competes with a fixed amount of 5-HIAA on the solid phase supporter for sites on the Biotinylated Detection Ab specific to 5-HIAA. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of 5-HIAA in tested samples can be calculated by comparing the OD of the samples to the standard curve.
