Beschreibung: 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.

Beschreibung: 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.

Beschreibung: Das Epoxy Embedding Medium Kit ist ein sehr weit verbreitetes Einbettungsmedium für die Elektronenmikroskopie. Die ursprünglich von Luft (1961) veröffentlichte Einbettungsformulierung eignet sich hervorragend für pflanzliches und tierisches Gewebe. Aufgrund der geringen Viskosität des Harzes dringt es schneller in die Gewebeprobe ein als Araldite und andere Polymere. Es härtet bei niedrigen Temperaturen leicht und gleichmäßig aus, wenn Dodecenylbernsteinsäureanhydrid (DDSA), Methylnadicanhydrid (MNA) und der Beschleuniger 2,4,6-Tris(dimethylaminomethyl)phenol (DMP-30) zugegeben werden. Während der Aushärtung kann es zu einer leichten Schrumpfung kommen. Dieses Kit ist zum Einbetten einer Vielzahl von Geweben geeignet, da mit diesem Harz durch die Verwendung von zwei verschiedenen Anhydridhärtungsmitteln (DDSA und MNA) ein breites Härtespektrum für einen bestimmten Gewebetyp erreicht werden kann.

Beschreibung: Ehrlich’s reagent III, Loeffler’s Methylene Blue. Methylene Blue was earlier recognized as a good nuclear stain, the staining solutions are always either aged or alkalized, if not both. More importantly it is an excellent stain for ribonucleic acid, which is the important stainable constituent of bacterial bodies, of lymphocyte and hemoportoal cytoplasm, and of nerve cell tigroid granules. It can also be employed in capsule stain. The capsule stain begins as a negative stain leaving the organisms colorless. The capsule are clearly seen as halo surrounding the bacterial cell. Another staining procedure is performed with nigrosin (Cat. No. 43925).

Beschreibung: Alcian Blue solution has been used in the histological staining of acidic glycosaminoglycans (GAGs; mucopolysaccharides) that are carboxylated or sulfated. Sulfated glycosaminoglycans appear to be the preferred substrate for alcian blue at pH 2.5. Alcian blue has been used to stain hyaluronan (HA), a nonsulfated GAG, but the intensity of the staining of HA is affected by the method of tissue fixation used. Alcian blue staining of GAGs in tissue may be modified through the addition of an electrolyte such as magnesium chloride.
