What is silver staining? Silver staining is a powerful and versatile technique used for the detection and identification of proteins in gels. This technique is accomplished by binding silver to the chemical terminal or side chains of amino groups, such as carboxyl and sulfhydryl groups. For decades, silver staining has been used to separate proteins … Read more
What is Auramine- Rhodamine Staining? Principle of Auramine- Rhodamine Staining Auramine and Rhodamine are nonspecific fluorochrome dyes that are attracted to acid-fast microorganisms. In the case of Mycobacteria, the dyes can selectively bind to the mycolic acid present in the cell wall, allowing the stain to penetrate. This compound is resistant to acid-alcohol decolorizer solutions. … Read more
Wright’s stain is a modified Romanowsky stain. In hematology laboratory, it is used for the staining of peripheral blood smear, bone marrow aspirates, and urine samples.
This stain was discovered by German chemist Gustav Giemsa, that’s why its called Wright Giemsa Stain.
Staining is a method used to boost the contrast of samples, usually at the microscopic scale.
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.
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.
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.
Bacterial cells contain nuclear material, made of single-stranded circular DNA, in contrast to eukaryotes. This genetic material is present within the membrane-bounded structure known as the nucleus. In case of prokaryotes the nuclear material is present within the nucleoid which lacks the nuclear membrane and does not follow the mitosis or miosis cell division. Some … Read more
Aim To distinguish between living and dead cells. Principle The viability Staining Method mainly used to detect living and dead cells in culture. This method is based on the fact that, certain changes take place in dead cells which result in these cells giving a different reaction to stains from that of living cells. Requirement … Read more
