Giemsa stain CAS NO 51811-82-6
General description
Giemsa is a versatile polychromatic stain, which is suitable for staining a diverse range of specimens. Giemsa's stain is frequently used for diagnostic purposes in hematology to differentiate the nuclear and cytoplasmic morphology of platelets, RBCs, WBCs, and parasites. It is frequently used in combination with other dye solutions as May-Grunwald's solution for Pappenheim (MGG) and Wright-Giemsa. The Giemsa stain was adapted to histology due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. Giemsa′s staining solution is composed of methylene blue, azure, and eosin.
Application
Giemsa stain has been used for the staining of cells and blood films. It is required for the staining of azurophil granules and is an excellent stain for inclusion bodies. Its applications can be seen in hematology for blood and bone marrow specimens, bacteriology, clinical cytology specimens, histological biopsies, and tumor samples.
Suitability
Certified for Giemsa stain for blood films and for the Wolbach′s Giemsa method for paraffin sections.

Uses | Giemsa Stain is used as a laboratory reagent and stain for microscopy. It is also used for the histopathologic detection of malaria and other parasites such as spirochete and protozoan. The stain is also been incorporated in differential staining between bacterial and human cells. The compound has been used in combination with May-Grunwald or Wright Stain (sc-203763) as a histological hematology stain. |
Uses | Giemsa stain has been used for the staining of cells and blood films. |
Definition | ChEBI: Azure A is an organic chloride salt having 3-amino-7-(dimethylamino)phenothiazin-5-ium as the counterion. It is used in making azure eosin stains for blood smear staining. It has a role as a histological dye and a fluorochrome. It contains a 3-amino-7-(dimethylamino)phenothiazin-5-ium. |
General Description | Modified Giemsa stain means when the pH of the Giemsa stain is changed from the usual 6.8 to 9.0. |
