Washing

Thorough washing of the tissue following fixation is extremely important. It may sometimes be necessary to wash for at least as long as the tissue has been fixed in order to remove excess aldehyde or other fixation residues which may cause non specific labeling. In some cases quenching the tissue with ammonium chloride is performed to neutralise aldehyde groups. The wash is best performed in a buffer having a tonicity similar to the natural tissue.
