甲醛溶液，中性缓冲，10%

10% Neutral Buffered Formalin is the most used fixative throughout the world for light microscopy. Formalin solution is the commercially obtained solution containing 37% w/w (40% w/v) of formaldehyde in water. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining.

Formaldehyde is both a non-coagulant and an additive fixative. Formalin fixation is thought to form cross links between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship. 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.
