Human PTK7 (Protein Tyrosine Kinase 7) ELISA Kit

Inactive tyrosine-protein kinase 7; PTK7; Colon carcinoma kinase 4; Protein-tyrosine kinase 7; Pseudo tyrosine kinase receptor 7; Tyrosine-protein kinase-like 7; CCK4

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 Human PTK7. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human PTK7. 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 Human PTK7, 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 Human PTK7 in the samples is then determined by comparing the OD of the samples to the standard curve.
