Haemocyanin synthesis in the midgut gland of the crayfish, Astacus leptodactylus, was stud­ied in vitro. The addition of exogenous copper into the culture medium reduces the synthesis of total proteins and of haemocyanin. ʟ-lactate, uric acid and dopamine, which modify the affini­ty of haemocyanin towards oxygen, do not influence the biosynthesis of the polypeptide.
