PGA5 ELISA Kit (Human)

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

Pepsin A; pepsin A-3; pepsin A-4; pepsin A-5; pepsinogen 3, group I (pepsinogen A) ; pepsinogen 4, group I (pepsinogen A) ; pepsinogen 5, group I (pepsinogen A) ; pepsinogen-3; pepsinogen-4; pepsinogen-5; Pg5; pregnancy-associated glycoprotein.

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 Pepsinogen A (PGA) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Pepsinogen A (PGA) . 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 Pepsinogen A (PGA), 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 Pepsinogen A (PGA) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
