Giemsa stain is a type of Romanowsky stain named after Gustav Giemsa, a German chemist who created a dye solution. It was primarily designed for the demonstration of malarial parasites in blood smears, but it is also employed in histology for routine examination of blood smears.

Giemsa stain is used to differentiate nuclear and/or cytoplasmic morphology of platelets, RBCs, WBCs, and parasites (1,2). The most dependable stain for blood parasites, particularly in thick films, is Giemsa stain containing azure B. Liquid stock is available commercially.

2024年1月26日 · Giemsa's stain is a member of the Romanowski group of stains, which are defined as being the black precipitate formed from the addition of aqueous solutions of methylene blue and eosin, dissolved in methanol. The variants of the Romanowski group differ in the degree of oxidation (polychroming) of the methylene blue stain prior to the precipitation.

2022年8月2日 · 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.

Below, you’ll find how to prepare Giemsa solution for various applications, Giemsa staining protocols according to sample type and application, as well as detailed quality information regarding our Giemsa formulation.

2023年12月4日 · Wright-Giemsa Staining is a technique that uses a combination of basic and acidic dyes to distinguish different parts of cells. The basic dyes, such as methylene blue and azure, are attracted to the cell’s acidic components, like the nucleus, resulting in …

GIEMSA - SHEEHAN’S MODIFIED MAY-GRUNWALD PURPOSETo permit differentiation of cells present in hematopoietic tissue. The stain is also used for the demonstration of some microorganisms. PRINCIPLE: The “neutral” dyes combining the basic dye methylene blue and the acid dye eosin, give a wide color range when staining.

Prepare a 1:10 dilution of Giemsa stain with phosphate buffer pH 6.8 and mix well. Fix bone marrow aspirate smear in absolute methanol for 10 -15 minutes. Fully cover the slide with May-Grünwald-phosphate mixture and incubate for 10 minutes.

ed Use: This recommended protocol is applicable for the visualization of blood parasites. Giemsa Stain offers the flexibility of varying the intensity of the stain by adjusting staining times. nd the stain to buffer ratio. pH buffer selection will also affect your stainin.
