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 (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
Papanicolaou stain can also be referred to as the pap stain, and the process that causes the stain is referred to as a pap smear.
Different stains have been developed over time to distinguish bacteria species, separating them morphologically and the specific characteristics they possess. The most popular stain is Gram staining, acid-fast staining, and endospore staining. Each stain aims at identifying and defining bacteria according to their forms and morphologies.
Different stains react or concentrate on different areas of a tissue or cell These properties can be utilized to highlight certain areas or regions. A few of the most well-known biological staining methods can be found below. If not otherwise indicated All of these dyes can be used on tissues and cells that are fixed as well as essential dyes (suitable for use in live organisms) are indicated.
Staining is a method used to boost the contrast of samples, usually at the microscopic scale.
This stain was discovered by German chemist Gustav Giemsa, that’s why its called Wright Giemsa Stain.
Immunoelectrophoresis (IEP) is the process in which proteins of a biological sample are first separated by electrophoresis and then allowed to react with specific antibodies inside a gel. It is the technique combining electrophoresis with immunodiffusion. In this method the sample like serum is placed on an agarose gel and an electric field is applied, … Read more
Northern blotting or Northern hybridization is a widely used technique in molecular biology to determine the molecular weight of mRNA and to measure relative amounts of mRNA present in different samples and for identifying alternatively spliced transcripts and multigene family members.
Cell membrane staining is the process in which the plasma membrane of a cell is visualized with the help of dyes or fluorescent probes. It is the thin outer covering of the cell, and it is normally transparent, so it cannot be seen clearly under a simple light microscope. It is the process where special … Read more
