AffiELISA® Human TSHRAb Kit: High Sensitivity Thyroid Stimulating Hormone Receptor Antiboby ELISA Detection

The AffiELISA® Human TSHRAb Kit uses competitive inhibition enzyme immunoassay technique. The provided microtiter plate comes pre-coated with Thyroid Stimulating Hormone Receptor Antiboby (TSHRAb) protein. To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Thyroid Stimulating Hormone Receptor Antiboby (TSHRAb) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. Afterward, the TMB substrate solution is added, initiating an enzyme-substrate reaction. To conclude the reaction, a sulphuric acid solution is introduced, causing a color change that can be measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Thyroid Stimulating Hormone Receptor Antiboby (TSHRAb) in the samples can be determined.
