Application

Tested for staining blood smears according to G. Clark (ed.), Staining Procedures, 4th edition, Williams & Wilkins, 173 (1981); together with May-Grünwald Solution for pap staining according to Pappenheim.

Principle

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.

Physical form

Solution of azure B/azure II-eosin/methylene blue 1:12:2 (w/w/w) in glycerol/methanol 5:24 (v/v); total dye content: 0.6 % (w/w)

Reconstitution

Fix 10 min. in methanol; air-dry; immerse 45 min. in Giemsa Solution; rinse with distilled water; air-dry
