Staining
Laboratory staining is a technique used to make certain structures or components within cells or tissues visible under a microscope. Staining can be used to highlight specific structures or molecules within a sample, allowing scientists to identify and study them more easily.
There are many different types of staining techniques that can be used in the laboratory, including:
- Simple staining: Simple staining is a basic staining technique that uses a single dye to color all the cells in a sample. This technique is used to differentiate between different types of cells or to identify specific structures within cells.
- Differential staining: Differential staining is a technique that uses multiple dyes to stain different structures within a cell differently. This technique is used to distinguish between different types of cells or to identify specific structures within cells.
- Gram staining: Gram staining is a differential staining technique that is used to identify bacterial species. It uses crystal violet and iodine as the primary stains, and a decolorizing agent and a counterstain to differentiate between different types of bacteria.
- Acid-fast staining: Acid-fast staining is a differential staining technique that is used to identify certain types of bacteria, such as Mycobacterium tuberculosis, which causes tuberculosis. It uses a primary stain called carbolfuchsin and a decolorizing agent to differentiate between different types of bacteria.
- Fluorescence staining: Fluorescence staining is a technique that uses dyes that fluoresce under UV light. This technique is used to identify specific structures or molecules within cells or tissues.
Overall, laboratory staining is an important technique that allows scientists to visualize and study specific structures or molecules within cells or tissues.

Vacuole Staining – Observation of Vacuoles under Microscope
A light microscope may be used to see and examine the vacuole's structure. While the vacuole doesn't stain as the other organelles of the cell (because it does not contain many constituents that stain) tests have demonstrated that staining is possible for this organelle because the vacuole's sap absorbs and stores dyes that are colored.

Albert Stain Principle, Procedure, Result
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.

Types of Stains used in Microbiology
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.

Cell Wall Staining by Dayr’s Method
The composition of cell wall varies from species to species, it has been reported that the main constituents of cell wall is chitin, hemicellulose, and cellulose. In addition, prokaryotic cell wall contains peptidoglycan (also known as murein and mucopeptide). Peptidoglycan is mainly composed of sugar, amino acids (peptide; amino acids + glycan; sugar).
