tcue1343 ELISA Kit for 17-Hydroxyprogesterone (17-OHP)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to 17-Hydroxyprogesterone (17-OHP) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled 17-Hydroxyprogesterone (17-OHP) and unlabeled 17-Hydroxyprogesterone (17-OHP) (Standards or samples) with the pre-coated antibody specific to 17-Hydroxyprogesterone (17-OHP). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of 17-Hydroxyprogesterone (17-OHP) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of 17-Hydroxyprogesterone (17-OHP) in the sample.
