With an H&E stain, red blood cells look like red doughnuts - round with a depression in the middle like a jelly doughnut with the filling slurped out. The white blood cells are light pink, roughly circular, with a dark purple-blue nucleus. Depending upon the type of white blood cell, there may also be bright red or blue-purple granular structures in the cytoplasm. The platelets are visible as light pink amorphous structures.
What else can I help you with?
How can you observe a white blood cell in a light microscope?
White blood cells can be observed in a light microscope by preparing a blood smear, staining the cells with a dye like Wright's stain or Giemsa, and then viewing them under high magnification. The cells will appear as small, irregularly shaped cells with a dark-stained nucleus and a lighter-stained cytoplasm.
What microscope is more useful to estimate red blood cells?
A hemocytometer is commonly used to estimate red blood cells due to its accuracy and ability to provide a direct count. Alternatively, a microscope with appropriate magnification and a hematology stain can also be used to estimate red blood cells in a blood smear.
Why use of ramanowsky stain?
Romanowsky stains, such as Wright's stain and Giemsa stain, are commonly used in the laboratory setting for staining blood smears to visualize and differentiate various blood cells like red blood cells, white blood cells, and platelets. These stains provide contrast that allows for easy identification of cell types and abnormalities under the microscope. They are versatile and widely utilized in hematology and microbiology.
Identify a stain that would be appropriate for improving definition of the blood cells?
Wright's stain is a commonly used stain in hematology that improves the definition of blood cells, particularly white blood cells. It consists of a combination of acidic and basic dyes, allowing for better visualization and differentiation of various blood cell types.
How to stain blood film by leishman stain?
1. stain with leishman stain for 3 minutes 2. poured with buffer solution for 10 - 15 minutes, make sure the blood film is flooded with the buffer solution. 3. rinse with distilled water to clean the remaining stain. 4. air dry. this is the most simple step and easy to remember! good luck!

Is diff-quick stain stains RBCs pink and WBCs purple?
Yes, that's correct. Diff-Quik stain stains red blood cells pink and white blood cells purple due to differences in the staining properties of these cells. This differential staining helps in distinguishing between the two types of blood cells under a microscope.
What is the function of a stain in microscope work?
As the cells are transparent, the components cannot be seen clearly through a microscope. We stain the cell so that we can see the components of the cell clearly through a microscope.
What is the pH of buffer in the romanowsky stain?
The pH of the buffer in Romanowsky stain is usually around 6.8 to 7.2. This pH range is optimal for staining blood cells and facilitating the differentiation of their morphological features under the microscope.
Why do white blood cells look purple?
White blood cells appear purple when stained with certain dyes, such as Wright's stain or Giemsa stain, used in laboratory settings for microscopy. These stains bind to different components within the cells, highlighting their structures and nuclei. The purple color results from the combination of the dyes interacting with the proteins and nucleic acids in the cells, making it easier to identify and differentiate various types of white blood cells under a microscope.

Can you heat fix blood smear before staining for bacterial examination?
You absolutely do not heat fix a blood smear before staining, that is, if you are looking at the blood cells. For bacteria, why wouldn't you culture it first and then heat fix, stain etc. I don't think heat fixing the blood stain would damage the bacterial cells so much as make it hard to differentiate the bacterial cells from the dead, shriveled, ruined blood cells, unless maybe you have like an electron microscope or something.
How are tzanck preparations done?
is done by smearing cells taken from a fresh blister or ulcer onto a microscope slide. The cells are stained with a special stain, such as Wright's stain, and then examined under a microscope for characteristic changes caused by a herpes virus
If you stain a wet mount of living cells with iodine what are you most likely to see under a microscope?
Iodine is commonly used to stain starch granules within cells. Therefore, if you stain a wet mount of living cells with iodine, you are most likely to see starch granules within the cells stained with a dark color under the microscope.
What criterion is used to identify reticulocytes?
A blood sample is observed under a microscope using a stain or dye which will cause the RNA of the reticulocyte to be visible. Reticulocytes also look larger than mature red blood cells.
