MGG Stain is used for staining of blood, bone
marrow smears and clinical cytological specimens.
Principle
 MGG contains alkaline methylene blue (a basic dye),
related azures (also basic dyes) and acidic eosin (an
acid dye) and Giemsa staining makes effect of azure
more prominent staining stains all cellular
components.
 The basic dyes carry net positive charges;
consequently they stain nuclei (because of the
negative charges of phosphate groups of DNA and
RNA molecules), granules of basophil granulocytes
and RNA molecules of the cytoplasm of white blood
cells.
 The eosin carries net negative charge and stains red
blood cells and granules of eosinophil granulocytes.
 The pH is a very critical factor in staining, so any
change will lead to wrong staining reaction.
