Various Types Of Hematoxylin
Eosin is pink and stains proteins nonspecifically. For histology the two most commonly used are Mayers Hematoxylin and Harris Hematoxylin.

Different types of haematoxylin can be made up depending on the mordant used the method of oxidation and the pH.
Various types of hematoxylin. Essentially the hematoxylin component stains the cell nuclei blue-black showing good intranuclear detail while the eosin stains cell cytoplasm and most connective tissue fibers in varying shades and intensities of pink orange and red. Progressive modified progressive and regressive. In areas of soft water a suitable alkaline solution can be used to blue hematoxylin such as 005 vv ammonia.
If you want to prepare your own staining solutions we offer Hematoxylin and Eosin dyes and other necessary chemicals and reagents. Use as a writing and drawing ink. Select from Harris Gills Numbers 1 2 or 3 Mayers Hematoxylin or alcoholic or aqueous Eosin Y.
Simple alcoholic or aqueous solu-tions made with hematoxylin are usually pale yellow-brown in colour. H E stain can be classified into three types. Progressive staining takes place without a differentiator for removing any excess dye after adding hematoxylin.
Staining nuclei either green red or blue respectively. Various formulations of Hematoxylin and Eosin are supplied as ready-to-use solutions in several package sizes. There are typically three types of HE stains.
Alum hematoxylin Purpleblue coloration Alum-hematoxylin stains nuclei various shades of purpleblue Specific staining Non-specific staining may also occur o Cytoplasm o Mucin. 1 g or 05 g Eosin in 100 ml DW 1 or 05 Aqueous Eosin 005 ml GAA and small amount crystal thymol preservative. Progressive staining occurs when the hematoxylin is added to the tissue without being followed by a differentiator to remove excess dye.
Hematoxylin can be prepared in numerous ways and has a widespread applicability to tissues from different sites. 2 Use as a histologic stain. Harris hematoxylin has a high mordant content whereas Mayers and Ehrlich hematoxylin has a high dye content hence Harris hematoxylin binds firmly to the tissues and results in enhanced nuclear staining.
Haematoxylin and its types. The addition of acids to hematoxylin solutions increases the selectivity of the stain for nuclei by reducing nonspecific background staining. Acetic acid is added to Gill type hematoxylins while citric acid is found in Mayers.
A Dictionary of Biology. Its mainly used to stain Mucin. Progressive modified progressive and regressive.
Hematoxylin staining and counterstains 6 Oxidation Hematoxylin itself is not a dye and it has to be oxidised to hematein which is a dye before it can be used. The hematoxylin stains cell nuclei blue and eosin stains the extracellular matrix and cytoplasm pink with other structures taking on different shades hues and combinations of these colors. Hematoxylin has a deep blue-purple color and stains nucleic acids by a complex incompletely understood reaction.
Use as a textile dye. TYPES OF EOSIN Eosin B. This process is called ripening and can be accomplished in two distinct ways.
Two types of bonds are involved in the fundamental reaction between a mordant dye and a mordant. Eosin Y Working Solution is a ready-to-use counterstain with the ability to distinguish between the cytoplasm of different types of cells by. Use as a histologic stain.
The stain shows the general layout and distribution of cells and provides a general overview of a tissue samples structure. In a typical tissue nuclei are stained blue whereas the cytoplasm and extracellular matrix have varying degrees of pink staining. The Eosin Y is the most common stain used as counter stain with hematoxylin because it colors back ground by color vary from pinkish to reddish 47.
Examples are Delafields haematoxylin and Ehrlichs haematoxylin. INTRODUCTION The word hematoxlin is drived from old Greek word Haimato blood and Xylon wood reffering to its dark red color in natural state. Other commonly used tinctorial nuclear counterstains are light green fast red toluidine blue and methylene blue.
Hematoxylin Hematein complexed with Al3 is the most common form of hematoxylin used for nuclear staining. This cause background staining to occur in charged slides. Various acids are sometimes added to hematoxylin solutions to reduce the pH.
Hematoxylin is only the drastic substance that these solutions contain. Hematoxylin Stain Harris is a ready to use high quality regressive hematoxylin that does not require filtering is completely mercury-free and does not contain glacial acetic acid or ethylene glycol. They both contain water.
Also use to stain metal ions eg iron lead etc. The next step to having a good stain is determining what type of HE stain is desired. 1 Extraction and purification.
Stains tissue components in various shades of blue pink red.
