Limulus chromatophorotropin: Action on isolatedUca legs and in various crustaceans

Abstract
Summary Limulus CNS chromatophorotropin causes melanin dispersion in isolated legs ofUca. Theophylline potentiation of extract activity suggests that the material may act through the adenylate cyclase-cAMP system. The extracts are also active on the chromatophores of 7 decapod species from 6 families.
