Descrizione

General description

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.

Application

Formalin solution (neutral buffered, 10%) has been popularly used as a general-purpose histological fixative to fix tissue samples.

• It effectively preserves the cellular and tissue morphology, maintaining the structural integrity required for microscopic examination.
• It is used for routine histological staining, providing clear and detailed images of cellular structures.

Fissativo istologico comunemente usato per fini generici.

Biochem/physiol Actions

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.

Features and Benefits

• 10% NBF is well-suited for large throughput laboratories.
• It requires a relatively short period of fixation.
• It can be used for the long-term storage of tissue.
