Description générale

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.It helps to preserve tissue samples by preventing decay and maintaining their molecular integrity.
Il s'agit d'un fixateur histologique universel d'usage courant.

Conditionnement

Item is packaged in a 20 L Cubitainer consisting of a plastic bladder inside of a cardboard box with an attached spigot.
