tcue432 ELISA Kit for Estrone (E1)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Estrone (E1) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Estrone (E1) and unlabeled Estrone (E1) (Standards or samples) with the pre-coated antibody specific to Estrone (E1). 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 Estrone (E1) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Estrone (E1) in the sample.
