How do you stain a blood smear with Diff Quick?
Diff-Quik solutions should be stored in air tight containers to avoid evaporation or spillage. Start by opening all three pots. Gently dip the slide into staining pot 1 (Fixative solution) for one second… … and remove. Repeat – dipping the slide a total of 5 times, each time lasting 1 second.
What is Wright’s blood stain?
Wright’s stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates, which are examined under a light microscope.
Why does Wright’s stain work for all blood types?
Wright’s stain is a type of Romanowsky stain, which is commonly used in hematology laboratory for the routine staining of peripheral blood smears. It is also used for staining bone marrow aspirates, urine samples and to demonstrate malarial parasites in blood smears….Results.
| Cells | Result |

| Platelets | violet to purple granules |
How is Wright stain prepared?
Preparing the dye solution Wright’s solution • Dissolve 0.25 g of BioGnost’s Wright’s stain in 100 mL of methanol while stirring and heating in water bath. Diluted Wright’s solution • Mix 20 mL of buffer solution, 150 mL of distilled/demineralized water and 30 mL of Wright’s solution.
What is the difference between Giemsa and Wright stain?
The main difference between Giemsa stain and Wright stain is that Giemsa stain is used to stain chromosomes to identify chromosome aberrations. But, Wright stain is used to differentiate blood cell types.
Why is differential staining important in microbiology?
Differential staining is a procedure that takes advantage of differences in the physical and chemical properties of different groups of bacteria. It allows us to differentiate between different kinds of bacterial cells or different parts of a bacterial cell.
What is the purpose of methanol in Wright stain?
The stain contains a fixative, methanol, and the stain in one solution. Thin films of blood are fixed with methanol to preserve the red cell morphology so that the relationship between parasites to the red cells can be seen clearly.
