haematoxylin การใช้

• Hence, acid solutions of alum haematoxylin become red.
• The photographical slide was processed, counterstained in haematoxylin and mounted for microscopy.
• "' Haematoxylin "'stain cell nuclei prior to examination under a microscope.
• It is easily identified in haematoxylin and eosin stained sections since it stains less intensely than dentin.
• Another alternative is the aluminium complex of oxidized brazilin, which differs from haematoxylin by only one hydroxyl group.
• In the early 1970s and in 2008, there were shortages of haematoxylin due to interruptions in its extraction from logwood.
• This property of simultaneously staining two different colours is different from other haematoxylin reagents e . g . alum-haematoxylin.
• This property of simultaneously staining two different colours is different from other haematoxylin reagents e . g . alum-haematoxylin.
• He created a few histological stains that bear his name, including an iron haematoxylin stain that is still widely used today.
• It stains some tissue in contrasting colors in a way similar to haematoxylin and eosin stain, as phosphotungstic acid binds to tissue proteins.
• Interestingly the active component of haematoxylin is the oxidised form, haematin, although this rarely acknowledged in the literature which refer to haematoxylin staining.
• 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.
• The tissue must also be stained, usually with haematoxylin and eosin, a pair of colorants that identify the acidic-basic nature of the cells.
• 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.
• 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.
• 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 ).
• 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.
