| Working Principle
|
May Grunwald-Giemsa stain (MGG) is a Romanowsky stain routinely used for staining air-dried cytological smears, blood and bone marrow smears. Cytological preparations from FNAC and serous fluids are normally processed with May Grunwald-Giemsa stain. It is useful for examining cellular morphology and is superior to PAP staining for examining the cytoplasm, granules, vacuoles and basement membrane.
The working principle of MGG stain is the same as other Romanowksy stains. Polychromatic Romanowksy stains contain different proportions of methylene blue (and reagent-related thiazine dyes such as azure B) as the cation (+ highly charged, basic) component and eosin Y as the anion (- highly charged, acidic) component. . The combination of cation and anion components produces the well-known Romanowsky effect or metachromasia.
The solvent methanol initially stabilises the cells. The basic stains carry net positive charges; consequently they stain nuclei (due to the negative charges of the phosphate groups of DNA and RNA molecules), basophil granulocyte granules and RNA molecules of the cytoplasm. Eosin carries a net negative charge and stains red blood cells and eosinophil granulocyte granules. |

| Application

Application of the staining method:
-Cover the preparation with 10 drops of "A-May-Grünwald solution". After 3 minutes proceed to the next step without pouring the reagent.
-Add 10 drops of "Buffer working solution" to the reagent in the preparation. Mix the two reagents by blowing or small oscillations. After 6 minutes, remove the reagent by shaking the slide.
-Immerse the preparation in a beaker of "Buffer working solution". After 1 minute, remove the slide and shake off the reagent.
-Immerse the preparation in a beaker of "Giemsa working solution". After 20 minutes, remove the slide and shake off the reagent.
Air-dry the smear and examine under a microscope with an immersion objective. Dehydrate the tissue section, clean, cover with synthetic resin and examine under the microscope. |
