MGG stain ( May grunwald giemsa stain) is Romanowsky stain.They are composed of two components azure B and Eosin Y. Azure B bind with anionic parts of cell-like DNA and stain them blue. While Eosin Y binds with cationic parts of cell-like protein, it stains them the red color.
Giemsa stain was first discovered by Gustav Giemsa in 1902 It is composed of polychromed methylene blue and eosin. These components allowed simultaneous differential staining of cells.
There are 4 types of Romanowsy stains
- Giemsa Stain
- Wright Stain
- Jenner’s Stain
- Leishman Stain

What is the optimun PH of may grunwald giemsa stain solution ?
Optimum PH is required for Giemsa stain. An Alkaline PH accentuates the basic dye staining. Therefore Optimum PH is 6.8 for staining all components of cells.
what are the requirements for May grunwald giemsa stain
- May Grunwald Stain powder
- Giemsa Stain powder
- Conical Flask
- Methanol (acetone free)
How to prepare giemsa stain working solution (giemsa stain composition)
- Add the weighed amount of Grunwald stain power in the conical flask. Add 100 methanol and mix well.
- Add the weighed amount of Giemsa stain is another conical flask and add 100 ml methanol and dissolve it.
- Warm both flask at 50C temperature for 15 minutes. Note: Mix well during warming.
- Both stains filter in clean bottles and store at room temperature in the darkroom.
may-grunwald giemsa stain cytology procedure (mgg stain)
- Prepare the smear and dry it.
- Fix the smear in absolute methanol for 4 to 5 minutes, after this dry it.
- Place the Giemsa stain 1:10 buffer on slid for 1 hour.
- Wash with water, blot, and dry.
- Examine under oil emersion lense.
How to dilute may grunwald giemsa
Giemsa stain diluted with 1:10 of water. This means 1 part of the stain was added in 10 parts of water.

what are the may-grunwald-giemsa stain components?
The May-Grünwald-Giemsa stain consists of two main components: the May-Grünwald stain and the Giemsa stain.
what is mgg stain?
MGG stain or simply Giemsa stain, is a widely used stain in hematological and cytological examinations. It is commonly used to stain blood smears and bone marrow aspirates for the identification of various blood cells and other cellular components.
which structure does giemsa stain?
Giemsa stain primarily stains the chromatin and nuclear components of cells. It is particularly useful for visualizing and distinguishing the different types of white blood cells (leukocytes) and their nuclei.
what does giemsa stain bind to?
Giemsa stain binds to various cellular components within the cells.It interacts with acidic components of the cells, such as nucleic acids (DNA, RNA) and proteins.
what is may grunwald giemsa stain used for?
May-Grünwald-Giemsa stain (MGG stain) is a versatile staining technique commonly used in hematological and cytological examinations. It is primarily used for the staining of blood smears and bone marrow aspirates to aid in the identification and evaluation of various cell types and cellular components.
