This Human Transmembrane 4 L6 family member 18 (TM4SF18) ELISA Kit employs a two-site sandwich ELISA to quantitate TM4SF18 in samples. An antibody specific for TM4SF18 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTM4SF18 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TM4SF18 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TM4SF18 bound in the initial step. The color development is stopped and the intensity of the color is measured.
