Variations of calcitonin-like immunoreactivity in the crustacean Orchestia cavimana during a molt cycle

Abstract

The investigation of calcitonin-like immunoreactivity performed in whole extracts of the terrestrial crustacean Orchestia cavimana using radioimmunoassay revealed large amounts of these peptides varying in concentration according to the stages of the molt cycle. Their level is maximum at the time of the exuviation. The results are then discussed regarding the particular calcium metabolism of this species in function of its terrestrial conditions of life. © 1989.
