The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.Assay procedure summary: 1. Prepare all reagents, samples and standards;2. Add 100µL standard or sample to each well. Incubate 1 hours at 37°C;3. Aspirate and add 100µL prepared Detection Reagent A. Incubate 1 hour at 37°C;4. Aspirate and wash 3 times;5. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;6. Aspirate and wash 5 times;7. Add 90µL Substrate Solution. Incubate 10-20 minutes at 37°C;8. Add 50µL Stop Solution. Read at 450nm immediately.Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Chorionic Gonadotropin Beta Polypeptide (CGb). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Chorionic Gonadotropin Beta Polypeptide (CGb). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Chorionic Gonadotropin Beta Polypeptide (CGb), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Chorionic Gonadotropin Beta Polypeptide (CGb) in the samples is then determined by comparing the O.D. of the samples to the standard curve.Research Area: Reproductive science; Research Use Only
