It also kills them, making it safe to handle pathogenic bacteria. Trichrome Staining Procedure. The cells in each compartment serve a different function, such as producing certain proteins or anchoring the outer walls of a vessel to the rest of the tissue. One disadvantage of gram staining is that the cells cannot be alive while being stained, so viewing live stained cells is impossible. 4. Haemotoxylin stains certain parts of the cell - like the nucleus - blue; Eosin stains other parts of the cell - such as the cytoplasm - red or pink.

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.
