Giemsa solution should never be diluted in PBS. Giemsa solution is typically diluted with either deionized water or a low molarity phosphate buffer. Weise and Sorsensen phosphate buffer solutions are typically used. Dilutions can range from 1:10 to 1:80. The most common range for dilutions are either 1:20 or 1:40.

General description
Modified Giemsa stain means when the pH of the Giemsa stain is changed from the usual 6.8 to 9.0.[1]
Application
Modified Giemsa stain may be used for the identification of each human chromosome by differentials staining.[1]
Biochem/physiol Actions
When blood films are stained using Giemsa Stain, the nucleus and cytoplasm of white blood cells take on characteristic blue or pink coloration. The use of purified eosin and thiazine dyes minimizes lot-to-lot variation.
Other Notes
Giemsa stain, modified, 0.4%, w/v, in buffered methanol solution, pH 6.8. Also contains stabilizers.
