Aldehyde Fuchsin For Elastic

Aldehyde fuchsin stains several different tissue constituents, among them elastic fibres. They stain deep purple on a light purple background, usually, and are quite easy to see. I suspect that the reason for the method not being used as much as it could be has more to do with the poor keeping qualities of the staining solution than the quality of the results. The solution is stable for just a few months, so must be frequently prepared.

Aldehydes and basic fuchsin can form large molecules in solution and, once again, these may be prone to forming bonds via van der Waals forces, as far as elastic fibres are concerned, although other processes may be involved with other tissue constituents that aldehyde fuchsin colours.
