10% Neutral Buffered Formalin


Cat. No.: 66312 Category:


Formalin is composed of formaldehyde (37 to 40% (w/v)), where 10% neutral-buffered formalin (NBF) is basically a 4% (v/v) formaldehyde solution diluted using phosphate buffer at neutral pH. 10% NBF is a commonly used general purpose histological fixative, widely employed in preparing samples for light microscopy. It is ideally suited for short-term sample fixation but equally efficient for long-term tissue storage and is compatible with targets such as low molecular weight proteins, peptides and enzymes. Our 10% NBF solution is specifically developed for use in multiple histological and cytological applications. The product has neutral pH and is supplied free of contaminants, thus minimizing the inconvenience caused from non-specific background staining and artifacts. 10% NBF forms crosslinks between the aldehydes and the proteins of the study samples that retains the original structure of the cellular components and preps the samples for successive processing and staining procedures.

• Used for fixing and storage of various tissue types
