what is the purpose of simple staining?

Answer 1

If you mean simple staining of microscopic specimens, the purpose is to add visual contrast to otherwise transparent objects, so they will be easier to see and study under the microscope.

Answer 2

Simple Staining

Answer 3

The simple staining is done to achieve several aims :
1. To provide appropriate contrasting background so that the object can be observed with relative ease. Most of the objects, tissue cells, microbes are transparent and light can pass through them . If this object is stained, the light is reflected and the object can be visualised easily.

2. Simple staining is useful to study the shape of the object.

3. Simple staining is useful to study the size of the object.

4. Simple staining is useful to study the arrangement of the cells eg. chains, bunch, paired arrangement in bacteria.

5. Only one type of dye (stain) is used in simple staining.

Answer 4

Aseptic procedures are those which are done in such a way as to keep microbial contaminants from getting in. Examples are surgical procedures, transfer of a sterile catheter from the O.R. kit to the patient, injections, and as in today's lab, the use of aseptic technique in transferring bacteria from a culture to a microscope slide for staining without contaminating the culture, the environment, or ourselves.
Simple Staining - Purpose is to make bacteria more visible. Only 1 stain used
with positive & negitive types

Answer 5

To enhance contrast in the normally colorless tissue sections, tissue sections are commonly stained. For light microscopic examinations, colored agents (chromophores) are used. For the electron microscope, electron-dense heavy metal salts are employed (e.g., lead citrate, uranyl acetate).

The earliest histologists used naturally occurring dyes to stain their sections. With the invention of chemical dyes a greater array of stains became available. Although there is some understanding of staining mechanisms, even today the precise mechanism of many stains is not known.

Students frequently hear or read that certain dyes are either basic or acidic. This is because synthetic dyes are prepared so that the coloring part of the dye is either acid (anionic) or basic (cationic) in its chemical behavior. The cationic or basic dye has an affinity for nuclei and ribosomes that exist in the tissue with a net negative charge and are termed basophilic; the anionic or acid dye has an affinity for positively charged cytoplasm and other components like mitochondria and cilia, which are then termed acidophilic structures. Thus:

Basic stain: [dye]+ OH-
stains basophilic structures, e.g., nuclei, ribosomes, GAGs

Acid stain: [dye]- H+
stains acidophilic structures, e.g., mitochondria, collagen

A tissue section contains many proteins that differ in their isoelectric points. At an ideal pH, certain tissue components will show a relative acidophilia whereas others display a relative basophilia.

Frequently, basic dyes (methylene blue, toluidine blue, thionine) will react with a specific tissue component and impart to it a color different from that of the dye itself. This phenomenon is called metachromasia and the cell or tissue components that exhibit it are said to be metachromatic.

Staining would just be a way of either detecting a specific structure or protein in a cell, while differential staining would highlight two different areas, thus using different dyes.

Answer 8

If you are referring to gram staining it can help to begin to identify the bacteria , possibly enough to provide all the needed information for treatment.
Other reasons for other staining includes better part visualization

Answer 9

staining is done to make the cells and tissues appear clear as our eyes can distinguish between different colours easily which can be got only after staining.

Answer 10

Uses only one dye and functions to observe and determine morphology an arrangement.
