Summary The performic acid (or acid potassium permanganate) pseudoisocyaninchloride technique (PSICN), when applied to formol-fixed paraffin-embedded sections of the hypothalamo-neurohypophysial system, causes to fluoresce intensely material with the same distribution as chrome-alum haematoxyphil neurosecretory material. It has been claimed that in vitro this technique does not react with oxytocin, but does react with neurophysin, the carrier (or precursor) polypeptide. Now however, using Rodeck's agar technique, which mimics closely conditions applying in tissue-sections, we have demonstrated that the PSICN technique will react in vitro with the octapeptide neuro-hormones, oxytocin and vasopressin.
