Melanin will reduce ferricyanide to ferrocyanide producing a blue coloured compound in the presence of ferric salts (Schmorl's reaction)
Gram stain
Giemsa stain is a type of Romanowsky stain used in cytogenetics and histopathology to stain chromosomes, blood cells, and microorganisms. It works by binding to the phosphate groups in nucleic acids, such as DNA and RNA, allowing for visualization of cellular structures under a microscope.
Yes, acid-fast stain is a type of differential stain.
The counter or secondary stain used in the Gram stain procedure is safranin.
The Wright stain is a combination of eosin and methylene blue dyes, while Giemsa stain is a mixture of eosin, methylene blue, and azure dyes. Giemsa stain is commonly used for staining blood smears to visualize parasites and bacteria, while Wright stain is used more for general cell morphology in blood and bone marrow specimens.
Gram stain
Neutralization involves using a substance to counteract the effects of an acidic or alkaline stain. The principle behind neutralization in stain removal is to restore a neutral pH level to the stained area, which can help break down and remove the stain effectively. This process helps to prevent further damage and ensures that the cleaning agent is more effective in removing the stain.
gram stain principle
Mould staining can be wiped off by Concrobium Mold Stain Eraser.
THe rubber absorbs the pen or pencil mark - hence, the mark is gone! think of blotting a stain from a carpet - the rag or sponge absorbs the stain ...same principle for pens and pencils

flagella stain Purpose: To determine the presence/absence and location of flagella on various microorganisms Principle: Because bacterial flagella are very thin and fragile a special stain (flagella stain) is prepared that contains a mordant. This mordant allows piling of the stain on the flagella, increasing the thickness until they become visible. Various arrangements of flagella are seen on different cells.
It is basically use to stain leukocytes,maleria prasite and trypanosomas. leisman stain contain 1st methylene blue dye, a basic dye, which gives color to an acidic component.2nd eosin dye,an acidic dye ,which gives color to a basic component. These dye differentiat the different component of blood.
The solubility principle can be applied to remove stains by dissolving the stain in a solvent that the stain is soluble in, such as using water to dissolve sugar stains. Additionally, using surfactants can help to break down the stain and improve its solubility in water, as seen in laundry detergents removing grease stains from clothes. Finally, leveraging the solubility of stains in acidic or alkaline solutions can help to neutralize and remove them, like using vinegar to dissolve mineral deposits in a coffee maker.
