Silver Staining – Principle, Procedure, Result, Uses

Silver Staining - Principle, Procedure, Applications

Silver staining is the process used for detecting and identifying proteins and nucleic acids in different gels, and it is highly sensitive in nature. It is the method where silver ions (Ag⁺) binds to different chemical groups present in proteins like carboxyl and sulfhydryl groups, and these ions is then reduced into metallic silver (Ag⁰). … Read more

Results of Grocott-Gomori’s Methenamine Silver Staining

Grocott-Gomori’s Methenamine Silver (GMS) stain is the histological staining method that is used mainly for the detection of fungal microorganisms in tissue sections and smears. It is the process that was first developed by Gomori and later modified by Grocott, and it is used because of its high sensitivity to demonstrate carbohydrates present in the … Read more

Calcofluor White Staining – Principle, Procedure, Results, Applications

Calcofluor White Staining

Calcofluor White (CFW) is a fluorescent dye that is used for the quick detection of fungi, yeasts, and some parasites. It is a stilbene derivative and it is the compound that absorbs ultraviolet light and then emits a visible blue light. It binds with β-linked polysaccharides like chitin in fungal cell walls and cellulose in … Read more

Production Media - Definition, Characteristics, Examples, Uses

What is Production Media? Production media is the nutrient-rich medium used to support the large-scale growth of microorganisms or cell cultures for the purpose of producing useful biological substances. It is designed in such a way that optimum growth conditions is maintained, and the metabolic activities of the organisms is supported for yielding products like … Read more
