Pan-species (General)

serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids

Competitive Inhibition

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Instant Estradiol (E2) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Instant Estradiol (E2) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Instant Estradiol (E2) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Instant Estradiol (E2) and unlabeled Instant Estradiol (E2) (Standards or samples) with the pre-coated antibody specific to Instant Estradiol (E2). 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 Instant Estradiol (E2) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Instant Estradiol (E2) in the sample.
