Giemsa stain
Giemsa Stain
Giemsa stain (pronounced: /'geem-sa/), is a type of stain used in cytology and histology. Named after the German chemist and bacteriologist Gustav Giemsa, it is primarily used for the staining of malaria parasites and other hematological studies.
Etymology
The term "Giemsa stain" is derived from the name of its inventor, Gustav Giemsa, a German chemist and bacteriologist who developed the stain in the early 20th century. The word "stain" comes from the Old English word "stænen," which means to color or dye.
Usage
Giemsa stain is used in cytology and histology to differentiate and identify cells and organelles. It is particularly useful in the identification of parasites, such as those that cause malaria, and in the study of chromosomes.
Procedure
The procedure for using Giemsa stain involves applying the stain to a slide containing the sample to be studied, then rinsing it off after a certain period of time. The stained slide is then examined under a microscope.
