Description: Giemsa stain is a versatile differential stain that is widely used in hematology for blood and bone marrow specimens, clinical cytology specimens, bacteriology, histological biopsies, and tumor samples. Giemsa's staining solution is composed of methylene blue, azure, and eosin. It is a major histological stain due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. The stain is frequently used in combination with other dye solutions: May-Grünwald’s solution for Pappenheim (MGG) and Wright-Giemsa.

Description: Formaldehyde is both a non-coagulant and an additive fixative. Formaldehyde is known to penetrate tissue quickly, but the fixation process may take a long time to form the various cross links with tissue proteins. Formalin fixation is thought to form cross links between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their <i>in vivo</i> relationship. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining. Although there is no true universal fixative, 10% neutral buffered formalin (NBF) is perhaps the most commonly used fixative throughout the world for light microscopy and is a somewhat forgiving fixative. Of the dozens and dozens of available fixatives, it is hard to imagine a fixative more commonly used than 10% NBF. 10% neutral buffered formalin is well suited for large throughput laboratories, and requires a relatively short period of fixation, but can also be used for the long-term storage of tissue.

Description: Osmium tetroxide (OsO₄) is a heavy tetrahedral, symmetrical molecule composed of osmium, a third-row transition metal. Osmium tetroxide is both a dye, and a non-coagulant fixative agent in electron microscopy primarily used for the examination of biological tissue components in the histopathology laboratory. Specimens are postfixed with osmium testroxide to ensure preservation of the lipids.
