Human CK-19/KRT19 (Cytokeratin 19) ELISA Kit

Human CK-19/KRT19 (Cytokeratin 19) ELISA KitThe Human CK 19 KRT19 (Cytokeratin 19) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Human CK 19 KRT19. 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 CK 19 KRT19 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to

The Human CK-19/KRT19 (Cytokeratin 19) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human CK-19/KRT19. 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 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 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 CK-19/KRT19. You can calculate the concentration of Human CK-19/KRT19 in the samples by comparing the OD of the samples to the standard curve.
