This was more apparent with the alkaline phosphatase (AP) chromogen than with the horseradish peroxidase (HRP) chromogen, so the marker with the lowest apparent avidity was conjugated to the more robust HRP complex and diaminobenzidine (DAB) chromogen in order to best preserve its signal throughoutthe process. The primary antibody HRP conjugation kit allowed fordirect marker-chromogen detection, eliminating the need for indirect complex reagents and reducing assay run time by approximately one hour from that of our standard indirect detection methods.
