Formalin 10% histological fixative, neutral buffered
Formalin

10% Neutral buffered formalin (NBF) is the most commonly used fixative for light microscopy. 10% NBF 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. Formalin fixation is thought to form between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship.
