The most basic reason that cells are stained is to enhance visualization of the cell or certain cellular components under a microscope. Also, note the cell shape of each. 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 throughout, A non-specific staining interaction between the DAB chromogen and the iron stain reaction product was observed when iron staining was done first. Considerable testing was performed to attain the optimal intensity of each chromogenic stain in order to achieve an acceptable visual combination). The procedure is performed to produce precluding information regarding the type of organisms that are directly present from the clinical specimens or from the growth on culture plates.
