产品描述
This assay employs the Sandwich enzyme immunoassay technique. Determine the level of Human TFF3(Trefoil Factor 3, Intestinal) in the sample. Add standard and sample to the microplate that have been pre-coated with Anti-Human TFF3(Trefoil Factor 3, Intestinal) antibody. After incubation, add Biotin-conjugated anti-Human TFF3(Trefoil Factor 3, Intestinal) antibody. It is then combined with HRP-conjugated streptavidin to form an immune complex, then incubated and washed to remove unbound enzyme, and then added to the chromogenic substrate TMB to produce a blue color, and converted to the final yellow under the action of acid. Finally, the absorbance (OD) value was measured at 450 nm. The concentration of Human TFF3(Trefoil Factor 3, Intestinal) in the sample was proportional to the OD value. The concentration of Human TFF3(Trefoil Factor 3, Intestinal) in the sample can be calculated by drawing a standard curve.
