The role of the Giemsa stain in cytogenetics

Abstract:
In just half a century since the human diploid chromosome number was correctly identified as 46, there has been a rapid expansion in our understanding of both the genetic foundation of normal human development and the development of various constitutional and acquired abnormalities. The ability to detect numerical and structural chromosomal abnormalities was made possible by the Giemsa stain. Despite the recent advent of powerful molecular-based cytogenetic techniques (e.g., fluorescence in situ hybridization, array-based comparative genomic hybridization), Giemsa-based chromosomal banding and staining techniques retain their crucial role in cytogenetics.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
