General description

Formalin solution, neutral buffered, 10% is the most commonly used fixative for light microscopy. 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. 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.

Application

Formalin solution, neutral buffered, 10% has been used as a popular general purpose histological fixative.[1][2]It helps to preserve tissue samples by preventing decay and maintaining their molecular integrity.
Popular general purpose histological fixative.
