Description: 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).

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: 3,3′-Diaminobenzidine tetrahydrochloride hydrate has been used in immunohistological staining procedure and <i>in situ</i> hybridisation. DAB (3,3′-Diaminobenzidine) is utilised in many applications for the visualisation of peroxidase activity. In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidised DAB forms an insoluble brown end-product for use in immunohistological and immunoblotting staining procedures.
