Interestingly the active component of haematoxylin is the oxidised form, haematin, although this rarely acknowledged in the literature which refer to haematoxylin staining.

Special stains that may be of use in the diagnosis include Masson's trichrome, Van Gieson's stain and phosphotungstic acid haematoxylin.

Basophilic dyes such as aniline or ( weakly ) haematoxylin highlight negatively charged components, and so bind to the phosphate backbone of the ribosomal RNA.

In current practice, microscopic analysis of haematoxylin and eosin stained section is the backbone in the diagnosis of breast cancer and other types of cancers.
16.
The tissue must also be stained, usually with haematoxylin and eosin, a pair of colorants that identify the acidic-basic nature of the cells.
17.
Before the use of any alternatives became firmly established, haematoxylin returned to the market, though at a higher price, and resumed its place in histopathology.
18.
In the presence of excess acid, aluminium hydroxide cannot be formed, thus causing failure of aluminium haematoxylin dye-lake to form, due to lack of OH " ions.
19.
The recommended histologic grading schema for RCC is the Fuhrman system ( 1982 ), which is an assessment based on the microscopic morphology of a neoplasm with haematoxylin and eosin ( H & E staining ).
20.
During staining, alum haematoxylin-stained sections are usually passed on to a neutral or alkaline solution ( e . g ., hard tap water or 1 % ammonium hydroxide ) in order to neutralize the acid and form an insoluble blue aluminium haematin complex.
