Human TSH ELISA Kit

Human TSH ELISA Kit employs a two-site sandwich ELISA to quantitate TSH in samples. An antibody specific for TSH has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TSH present is bound by the immobilized antibody. After removing any unbound substances, a HRP conjugated antibody specific for TSH is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TSH bound in the initial step. The color development is stopped and the intensity of the color is measured.
