EDN2 ELISA Kit (Rat)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Endothelin 2 (EDN2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Endothelin 2 (EDN2) 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 Endothelin 2 (EDN2) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Endothelin 2 (EDN2) and unlabeled Endothelin 2 (EDN2) (Standards or samples) with the pre-coated antibody specific to Endothelin 2 (EDN2) . 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 Endothelin 2 (EDN2) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Endothelin 2 (EDN2) in the sample.
