Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in Biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes. Stains may be used to define and examine bulk tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells, for instance), or organelles within individual cells.
In biochemistry it involves adding a class-specific (DNA, proteins, lipids, carbohydrates) dye to a substrate to qualify or quantify the presence of a specific compound. Staining and fluorescent tagging can serve similar purposes. Biological staining is also used to mark cells in flow cytometry, and to flag proteins or nucleic acids in gel electrophoresis.
Staining is not limited to biological materials, it can also be used to study the morphology of other materials for example the lamellar structures of semi-crystalline polymers or the domain structures of block copolymers.

Which is an example of a dye used in a simple stain?
Methylene blue
Can you tell an organisms gram stain by simple staining?
Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
What does the simple stain tell us about the bacteria?
The result of simple staining of microorganisms is that they can be identified and studied under a microscope.
What are the advantages of the simple stain technique over the negative stain technique?
Negative staining has a dark contrasted background and the bacteria is white. Simple staining has a white background and bacteria is the color depended on your stain color.Negative staining when prepared is NOT heat fixed but simple staining when prepared is heat fixed. Heat fixed means when preparing slide with bacteria on it, it is passed over some type of flame, like a Bunsen burner flame, three times or four times.
What does a simple stain of bacillus megaterium look like under a microscope?
Simple or gram? Simple uses methylene blue, gram uses crystal violet
Which is an example of a dye used in a simple stain?

Why is a stain called a stain?
It's simple, because it's a stain.
What is the value of simple stain?
A simple stain like iodine can make cell parts show up that would otherwise be nearly invisible since they are colorless.A simple stain like iodine will reveal a cell's morphology.
Why is the gram stain technique more valuable than the simple stain technique in the diagnostic laboratory Under what circumstances might the simple stain be preferable to the gram stain technique?
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.
Do electronic cigarettes stain walls?
simple answer is NO
Can you stain on top of the old stain?
yes you can and the stain can change colors if there is a juice stain for example thats red and a grass stain the stain color could change
What is an advantage of a simple stain over a wet mount?
You can see clearer images in the simple stain technique rather than the wet mount technique...
What is stain on shirt an example of?
it is an example ostrawberry jam
What information can be obtained from a simple stain?

Gram stain is not a simple stain because simple stains do not use two or more stains. Gram stain is a differential stain differentiating between Gram positive (blue-black) and Gram negative (pink-red).
Why is the size more accurate in a negative stain than a simple stain?
since you do not heat fix the slide when you use a negative stain the cells do not shrink or become distorted
