The blue stain is called crystal violet. It can color the bacteria a blue color only if the cell wall is very thick. We then call that bacteria a Gram+ bacteria. Knowing the Gram test (+ or-) and the shape of the bacteria, we have a quick idea of what it might be. Then what antibiotic could be given gives a head start on a treatment. This can take as little as a few minutes. Further tests are usually done later on. They can take 24 to 36 hours to get a result.

Why was it important to steam the slides in the ziehl-neelsen method?
Steaming the slides in the Ziehl-Neelsen method is crucial because it facilitates the penetration of the carbol fuchsin dye into the waxy cell wall of mycobacteria, such as Mycobacterium tuberculosis. The heat helps to melt the lipid components of the cell wall, allowing for better dye uptake and subsequent visualization. This step is essential for accurately identifying acid-fast bacilli under the microscope, which is vital for diagnosing tuberculosis and other mycobacterial infections.
What can you put on a specimen to make it easier to see through the microscope?
phenyle blue was a common dye used in biology when I was in college. You need to check to see what the particular item you are wanting to look at will react with first, though.
What happens when you put dye in water?
If you boil it, the water will boil and the dye will not, leaving you with dye.
What is fado meter?
It is an instrument used to determine the resistance to fading of a pigment or dye on natural or synthetic polymeric materials
What is the name given to the process that caused the movement of the dye?
The process that caused the movement of the dye is called diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in a uniform distribution of the dye molecules. This process is driven by the random thermal motion of molecules and is a fundamental concept in chemistry and biology.
Name the fluorescent dye used in the fluorescent microscope?
One commonly used fluorescent dye in microscopy is fluorescein isothiocyanate (FITC). It is known for its high brightness and stability under illumination.
What is the function of staining rack?
it helps in staining many slides at a time, as when we put many slides on a rack we can pour dye simoultaneously on all the slides and it will also help in reducing loss of extra dye or stain.
Can you use food colouring to dye specimens for a microscope slide?
Yes, you can use food coloring to dye specimens for a microscope slide. However, food coloring is not as effective or long-lasting as specialized dyes used in laboratories. It may also interfere with the clarity of the specimen when viewed under a microscope.
What is staining rack?
A staining rack is a laboratory tool used to hold and organize slides during the staining process. It typically has grooves or slots where slides can be securely placed to prevent them from moving or touching each other while applying different staining solutions. Staining racks help in efficient and uniform staining of multiple slides at once.
What is a 5 letter word for microscope dye?
eosin
What is it called to add dye to a specimen under a microscope?
to stain.
Thin clear rectangular pieces of glass upon which specimens are mounted before being viewed under a microscope?
The piece of glass used to observe specimens under a microscope is called a slide. Sometimes a thin piece of glass is used to cover the specimen. This is called a coverslip. Coverslips and slides can be made of glass, quartz or plastic, as long as these items are totally transparent and do not introduce any distortion. Sometimes the material may be tinted in order to add contrast, although this is usually done with dye.
What is methyl green dye?
Methyl green dye is a synthetic dye commonly used in biology and histology for staining cell nuclei. It binds to DNA and RNA molecules, allowing for visualization and study of cellular structures under a microscope. It is commonly used in combination with other stains to enhance contrast and identification of specific cell components.
Why was it important to steam the slides in the ziehl-neelsen method?

How infusing dye into cells helps treat diseases?
The dye will colour the cell, making the cell easier to view through a microscope.
What dye do we use to dye cheek cells?
To dye cheek cells, methylene blue is commonly used. This dye stains the cell nuclei and helps to visualize the cells under a microscope. It enhances the contrast between the cells and their background, making it easier to observe cellular structures. Other dyes, such as iodine or Giemsa stain, can also be used depending on the specific needs of the observation.
What is the name of the plant is used to dye wool yellow?
Saffron is used to dye fabrics yellow. There are also some synthetic dyes which are used because saffron is very expensive.
