Why stain should not allow remain on the slide to long?
Leaving a stain on a slide for too long can lead to the over-staining of the sample, making it difficult to differentiate between different structures or cells. This can result in a loss of contrast and clarity in the sample, affecting the quality of the observation. Additionally, prolonged exposure to the stain can lead to fading or degradation of the sample over time.
What the precaution on negative stain?
One precaution when using negative staining is to ensure that the sample is completely dry before applying the stain. Any presence of water can affect the staining process and result in inaccurate visualization of the sample. Additionally, it is important to handle the stain carefully, as some negative stains can be toxic or corrosive.
Do characteristic properties change when sample changes?
Characteristic properties of a substance do not change when the sample changes. These properties, such as melting point, boiling point, density, and chemical reactivity, are inherent to the substance itself and remain constant regardless of the size or form of the sample.
What is the purpose of methyl alcohol in Leishman's stain?
Methyl alcohol in Leishman's stain serves as a solvent to help dissolve the dyes and other components in the stain solution. It also functions as a fixative to help preserve the cellular structures of the sample being stained.
Is uranyl acetate a negative stain?
Yes, uranyl acetate is used as a negative stain in electron microscopy.
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.

Can you help me find a stain match for my furniture?
Yes, you can find a stain match for your furniture by bringing a sample of the furniture's wood to a hardware store or home improvement store. They can help you find a stain that closely matches the color and finish of your furniture.
Can you help me find a wood stain color match for my furniture?
Yes, you can bring a sample of your furniture to a home improvement store and ask for assistance in finding a wood stain color that matches it.
How does differential scanning calorimetry work to measure the heat flow in a sample during temperature changes?
Differential scanning calorimetry (DSC) measures the heat flow in a sample as its temperature changes. It does this by comparing the heat flow in the sample to a reference material as both are heated or cooled at the same rate. The difference in heat flow between the sample and the reference material is used to determine the changes in the sample's thermal properties.
What color is an eosinophil stain?
Eosinophil stain is typically pink or red in color. It is used to differentiate cells in a sample and can help visualize eosinophils, which are a type of white blood cell.
What is the function of tincture iodine in trichrome stain?
Tincture iodine in trichrome stain is used as a mordant to enhance the staining of collagen fibers. It helps to improve the contrast and visibility of collagen in the tissue sample.
Suppose you are viewing a smear of a pure sample and you see both pink-red and purple cocci what is going on here?
The sample result is unclear. A number of variables could contribute to mixed results including contaminated equipment, not enough iodine when staining the sample, too much ethanol when rinsing, or not the sample did not heat long enough.
What is the counterstain in a spore stain?
The counterstain used in a spore stain is usually safranin or basic fuchsin. It is used to stain the vegetative cells or any background material that may be present in the sample, allowing the endospores to stand out and be clearly visible under the microscope.
