Stain vs. Dye in Histology
Main DifferenceThe main difference between stain and dye in histology is that stain is usually a combination of numerous dyes, whereas dye is a substance that highlights extracellular or intracellular elements of a tissue.

Stain normally used for biological specimens; conversely, the dye is used for normal purposes like staining clothes.
Stain vs. Dye in Histology
The stain is a purified form, and it does not contain impurities; on the contrary, a dye is a crude form of color that contains impurities.
Stain vs. Dye in Histology
The stain is produced with great attention or precautions and with extra fine conditions.

Various examples of stain are toluidine blue, Wright’s stain, H&E, Masson’s trichrome stain; on the flip side, some examples of dye are pyronin G, Aniline blue, Methyl green, orange G.

What is Stain?
The stain is generally a mixture of various dyes that enhance the contrast of biological specimen under in microscopic image. Normally, most cells that makeup tissues are transparent and colorless. That’s why to make the cells observable when observing under a microscope the tissues are stained in a specific way. Various chemical reagents are used in the technique of staining are the stains. Each dye present inside the stain is specifically accentuated a particular chemical object within a tissue. Hence, many constituents of tissues can be seen and observe in various contrasting colors under the microscope. Therefore, it means that stains give a contrasting shade to the microscopic slides and biological specimen. Stain process is not just limited for giving contrasting colors to biological specimen but can also be used to examine the structure of many other materials such as the spherical structures of block copolymers and the lamellar structure of partial-crystalline polymers. The stain is a purified form, and it does not contain impurities in its structure. The stain is produced with great attention or precautions and with extra fine conditions.
Types of Stain
- In Vivo Stain: In vivo stain is the method used to stain or dyeing living tissues.
- In Vitro Stain: In vitro stain is the process which includes the coloring of structures or cells that have been removed, or in other words, it is used to stain non-living tissues.
Examples
Various examples of stain are toluidine blue, Wright’s stain, H&E, Masson’s trichrome stain.
What is Dye?
A dye is a generally a single component which is contained in a strain. A particular dye can be used to accentuate a specific chemical object within a tissue. Hence, to accentuated many constituents in the same slide, then a mixture of several types of dyes should be used. Dye is a crude form of color that contains impurities. The dye is used for normal purposes like staining clothes. The two general central types of dye are acidic dye and basic dye. Basic dye usually deals with acidic/anionic constituents of the tissue, for instance, a nucleic acid. Acidic dye normally reacts with basic/cationic components of the tissue, for instance, proteins.
Basic Dye
- Methylene Blue: Blue color
- Pyronin G: Red color
- Toluidine Blue: Blue color
- Methyl Green: Green color
Acidic Dye
- Aniline Blue: Blue color
- Eosin: Red color
- Acid fuchsin: Red color
- Orange G: Orange color
ConclusionAbove discussion concludes that the stain is usually a mixture of several dyes and it is used to give contrast to the tissue, whereas dye is a substance that highlights extracellular or intracellular elements of tissue and used for usual purposes like staining clothes.
