Immunological relationships between neuropeptides from the sinus gland of the lobster Homarus americanus, with special references to the vitellogenesis inhibiting hormone and crustacean hyperglycemic hormone.
Antisera raised in guinea pigs against four major neuropeptides purified from sinus glands of the lobster, Homarus americanus, were used to study the immunological relationships between several sinus gland peptides. On the basis of their behavior in ELISA and in absorption procedures, three groups of peptides are defined. Two groups may be related to the crustacean hyperglycemic hormone (CHH groups); the third one is composed of three immunologically identical peptides and, since one of these peptides was characterized in previous studies as a vitellogenesis inhibitor, is referred to as VIH group. This closely meets our present knowledge about the physiological effects and biochemical characteristics of these neuropeptides and gives immunological insights on the question of molecular polymorphism of lobster neurohormones.
