Descripción: 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.
