How do you make a 10% Giemsa stain?
Therefore, 4.5 mL of Giemsa stock solution should be mixed with 40.5 mL of buffered water to prepare the required amount of 10% Giemsa working solution for staining 15 individual blood films.
What is Giemsa stain method?
Giemsa stain is a gold standard staining technique that is used for both thin and thick smears to examine blood for malaria parasites, a routine check-up for other blood parasites and to morphologically differentiate the nuclear and cytoplasm of Erythrocytes, leucocytes and Platelets and parasites.
Why do we dilute Giemsa stain?
Giemsa stain (3 ml) is diluted with buffered distilled water (100 ml) and is the stain of choice for demonstrating the presence of parasites in blood smears. Since distilled water is slightly acid, it was necessary to buffer it to obtain a pH of 7.0 to 7.4, with the optimum pH being 7.2 to 7.4.
What chemicals make up the Giemsa stain?
Giemsa solution is composed of eosin and methylene blue (azure). The eosin component stains the parasite nucleus red, while the methylene blue component stains the cytoplasm blue. The thin film is fixed with methanol.
How does May Grunwald Giemsa stain work?
May-Grunwald-Giemsa staining method is used for morphological inspection and differential counting of blood cells. May-Grünwald staining combines the effect of acidic eosin and alkaline methylene blue. Giemsa staining makes effect of azure. This staining stains all cellular components.
What does Giemsa stain?
Giemsa stain is a classic blood film stain for peripheral blood smears and bone marrow specimens. Erythrocytes stain pink, platelets show a light pale pink, lymphocyte cytoplasm stains sky blue, monocyte cytoplasm stains pale blue, and leukocyte nuclear chromatin stains magenta.
Is Giemsa stain acidic or basic?
Principle of Giemsa Stain Azure and eosin are acidic dye that variably stains the basic components of the cells like the cytoplasm, granules etc. Methylene blue acts as the basic dye, which stains the acidic components, especially the nucleus of the cell. Methanol act as a fixative as well as the cellular stain.
