How do you think the stain changes the sample?
A stain is the result of an interaction between substances.
Is uranyl acetate a negative stain?
Yes, uranyl acetate is used as a negative stain in electron microscopy.
How does a gram variable organisms appear under the microscope?
Gram-variable organisms can appear inconsistently colored under a microscope after a Gram stain procedure. Some cells may take up the crystal violet stain and appear purple (Gram-positive), while others may not retain the stain and appear pink (Gram-negative) after the counterstain (safranin) is applied. This variability can be due to differences in cell wall structure or damage to the cells. Consequently, a mixed population of purple and pink cells can be observed in the same sample.
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.
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.
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.

Is uranyl acetate a negative stain?
Yes, uranyl acetate is used as a negative stain in electron microscopy.
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.
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.
Can a human urine stain appear white on black clothing?
NO
What would you observe if you decolorized your slide too much?
If you decolorized your slide too much, you would likely have difficulty seeing the sample under the microscope. Over-decolorization can remove the stain from the cells or tissue, making them appear faint or transparent. This can impact your ability to accurately study the morphology or characteristics of the sample.

What is structural characteristic of monocyte?
Neutrophils have a multilobed nucleus that can appear to be multiple nuclei. The granules of a neutrophil are very fine and stain a pale lavender.
How would an endospore stain of e coli appear?
Negative cocci red
