Test Principle: This CLIA kit uses the Sandwich-CLIA principle. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human CK-19/KRT19. Samples or Standards are added to the micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CK-19/KRT19 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 CK-19/KRT19, biotinylated detection antibody and Avidin-HRP conjugate will appear luminescence. The Relative light unit (RLU) value is measured by the Chemiluminescence immunoassay analyzer at 425nm. The RLU value is positively associated with the concentration of Human CK-19/KRT19. You can calculate the concentration of Human CK-19/KRT19 in the samples by comparing the RLU value of the samples to the standard curve.
Cross reactivity: This kit recognizes Human CK-19/KRT19 in samples.No significant cross-reactivity or interference between Human CK-19/KRT19 and analogues was observed
