Test Principle: This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human CA19-9. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CA19-9 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human CA19-9, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human CA19-9. You can calculate the concentration of Human CA19-9 in the samples by comparing the OD of the samples to the standard curve.
Cross Reactivity: This kit recognizes Human CA19-9 in samples. No significant cross-reactivity or interference between Human CA19-9 and analogues was observed
Recovery Rate: 80%-120%
Precision: Both intra-CV and inter-CV are < 10%.
