产品描述
This assay employs the Sandwich enzyme immunoassay technique. Determine the level of Human CA125(Carbohydrate Antigen 125) in the sample. Add standard and sample to the microplate that have been pre-coated with Anti-Human CA125(Carbohydrate Antigen 125) antibody. After incubation, add Biotin-conjugated anti-Human CA125(Carbohydrate Antigen 125) 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 CA125(Carbohydrate Antigen 125) in the sample was proportional to the OD value. The concentration of Human CA125(Carbohydrate Antigen 125) in the sample can be calculated by drawing a standard curve.
