Principle of the Assay
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 Pig ET-1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Pig ET-1. 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 Pig ET-1, 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 Pig ET-1 in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision
AssayCVMethod
Intra-assay (precision within an assay)< 8%Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay (precision between assays)< 10%Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
Recovery

Matrices listed below were spiked with certain level of recombinant ET-1 and the recovery rates were calculated by comparing the measured value to the expected amount of ET-1 in samples.
