Classic Wright-Giemsa Fuccillo Stain

Classical Wright–Giemsa Fucillo Stain is a Romanowsky-type formulation designed for differential staining of peripheral blood smears, bone marrow specimens, and cytologic preparations. The Fucillo modification provides balanced nuclear and cytoplasmic staining, improved color stability, and clear differentiation of leukocyte populations, erythrocytes, platelets, and blood-borne parasites. Suitable for hematology, cytology, microbiology, and research laboratories, it supports manual differentials, morphology evaluation, and teaching applications. Compatible with standard Wright–Giemsa protocols and automated or manual staining systems, it delivers consistent, reproducible results for routine laboratory use.
