The 6-SMT ELISA is a competitive immunoassay using a capture antibody technique (8). A polyclonal antibody specific for rabbit immunoglobulin has been coated onto the microtiter plate provided in the kit. During the first 3-hours incubation, 6-SMT present in the pre-diluted urine samples, Controls and ready to use Calibrators, respectively, compete with biotinylated 6-SMT for the binding sites of a highly specific rabbit anti-6-SMT antibody, while the formed (biotinylated) 6-SMT-antibody complexes are captured by the second antibody coated on the wells. After washing, the Enzyme Label, streptavidin conjugated to horseradish peroxidase (HRP) is added which binds during a second 30-minutes incubation step to the 6-SMT-biotin-antibody complexes captured on the coated wells. Unbound Enzyme Label is then removed by a second washing step and TMB substrate (tetramethylbenzidin) is added to the wells. In a third 30-minutes incubation step, a colored product is formed in inverse proportion to the amount of 6-SMT originally present in the sample. The color turns from blue to yellow after the addition of an acidic Stop Solution and can be measured at 450 nm. See instructions for use for references.
