The microtiter plate provided in this kit has been pre-coated with an antibody specific to Zymogen granule protein 16. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for Zymogen granule protein 16 and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain Zymogen granule prote
