[Electronmicroscopic-histochemical demonstration of acid mucopolysaccharides using cationic ferrocenyl compounds (author's transl)].

Long-chain ammonium compounds with ferrocenyl groups were synthesized and used for the light (sudanophilia) and electron microscopic (electron dense staining by the iron of the ferrocenyl group) localisation of acid mucopolysaccharides. At least 5 of the 39 prepared ammonium salts produce a very good contrast. Cetyl-ferrocenylmethyl-dimethyl ammonium chloride has been found to be the best blocking agent and stain for acid polysaccharides.
