A student can use a stain called methylene blue to make nuclei more visible under a microscope. Methylene blue is commonly used in biology and histology to stain cells and highlight structures like nuclei.
you can get methylene blue powder from a scientific store, it comes in powdered form. its pretty soluble in water and alcohol etc. the stain is made by dissolving an appropriate amount on methylene blue in a solvent, e.g for 0.1 dissolve 0.1% gram of methylene blue in 100 gram water, for 9% dissolve 9 grams
It is basically use to stain leukocytes,maleria prasite and trypanosomas. leisman stain contain 1st methylene blue dye, a basic dye, which gives color to an acidic component.2nd eosin dye,an acidic dye ,which gives color to a basic component. These dye differentiat the different component of blood.
It depends on what tissue you're looking at, what you want to stain, how the tissue has been stored... Besides very specific staining, there are different types of staining. For example, immunohistochemistry, which uses antibodies to stick coloured stains to cell surface receptors. Or, chemical staining - the most common is H&E staining (haemotoxylin & eosin), so if you're just having fun in a lab and want to see general structures of cells, use this one.
A methylene blue skin stain typically lasts for a few hours to a day, although it can vary based on the concentration used and individual skin characteristics. The stain can fade faster with rubbing or washing the area.

Methylene blue can be used to prepare slide for animal cells. For example, if you want to examine a piece of your cheek cell, you would take a piece of cotton wool and rub it on the inside of your cheek and the rub it on a microscope slide, the you add a little distilled water and then a drop of methylene blue. The final step you would take, is to cover the slide with a cover slip, then place it under the microscope.
A common chemical used to make specimens visible under a microscope is a stain, such as hematoxylin and eosin (H&E) stain. Stains are designed to highlight specific structures or components of the specimen by adding color contrast.

Because negative staining requires the use of an acidic stain, which will not penetrate the cells because of the negative charge on the surface of the bacteria. As a result, the unstained cells can be easily identified against the colored background.
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.

Methylene blue is an appropriate dye because it readily binds to the negatively charged components of bacterial cells, such as nucleic acids and proteins. This binding allows for clear visualization of bacterial morphology and intracellular structures under a microscope. Additionally, methylene blue is a relatively simple and cost-effective stain to use in microbiology.

You can use a basic stain such as methylene blue to make the amoeba more visible under a microscope. The stain will bind to specific parts of the amoeba, making its structures easier to observe. It is important to follow proper staining procedures to avoid damaging the organism.
