What is a white blood cell that fights bacteria and stains neutral?
Neutrophils are white blood cells that specialize in fighting bacterial infections. They are called neutral because their granules do not stain strongly with acidic or basic dyes.
What blood cell granules stain bright orange red when you use Wright's stain?
Eosinophils are the blood cells whose granules stain bright orange-red when using Wright's stain. This staining highlights their role in immune responses and inflammation.
Which white blood cell type has granules that stain dark purple in response to alkaline dye?
Basophils are the white blood cell type that has granules that stain dark purple in response to an alkaline dye. These granules contain substances such as histamine and heparin, which play a role in inflammatory reactions and allergic responses.
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.
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.
What are polys in a blood test?
polys or PMN's - polymorphonuclear leukocytes. Cells that contain large visible granules are sometimes called granulocytes. They can be separated into 3 distinct cell lines, based on the reaction of the granules to the most commonly used stain in Hematology, the Wright stain. The stain is a pH based stain. Structures that favor the basic stain stain dark blue or basophilic; while those that favor the acid stain, eosin, stain bright red-orange. Some structures seem indifferent to the stain and are called neutral. The most numerous cell line of the granulocytes contain both light blue and light pink granules. As a result they are called neutrophils. This cell line is considered the first line of defense against most bacteria. It takes 6 steps for this cell to mature from a myeloblast to a fully mature cell. There have been several different ways to identify these cells so the following names are more or less synonymous: The most mature cells is called polymorphonuclear leukocytes (polys or PMN's) or segmented neutrophils (segs). One step from fully mature is the band or nonsegmented cell. Both these cells types are functional; the older one seems just a little bit faster. These cells are usually between 50 - 70% of all of the cells seen in a normal differential performed on an adult. These numbers do not work for infants and young children.
What part of plant cells relate to neutral red stain?
Neutral red stain is typically absorbed by the vacuoles of plant cells, which are membrane-bound organelles that store various substances such as pigments, nutrients, and waste products. The red color of the stain accumulates in the vacuoles, allowing for visualization of the vacuolar structure in plant cells.
What is the structural characteristic of a eosinophils?
They contain a bilobed nucleus and their granules stain red, due to the eosin dye. Plus, the granules themselves look almost crystalline. Don't get them confused with basophils which also have a bilobed nucleus BUT basophils granules do not stain well (and when they do they stain blue) in comparision.

How can granulocytes be identified from agranulocytes?
Granulocytes can be identified when their cytoplasmic granules are stained with Wright's stain. Agranulocytes do not have cytoplasmic granules so they will not have stained granules.
Principle of May-Grünwald stain?
The May-Grünwald stain is a vital staining technique used primarily in hematology to visualize blood cells and their components. It relies on a combination of eosin and methylene blue, which selectively stain the cytoplasmic components and nuclei of cells, respectively. The eosin imparts a pink color to eosinophilic granules and cytoplasm, while methylene blue stains the nuclei blue, allowing for differentiation of various cell types. This staining method is particularly useful for identifying abnormalities in blood smears.
