Hemolymph Insulin-Like Peptides (ILP) Titers and the Influence of ILP and Mammalian Insulin on the Amino Acid Incorporation in the Mantle Collar In Vitro in Helisoma (Mollusca).


In Helisoma duryi, the periostracum is the outermost organic layer of the shell and it is secreted by the mantle collar. Addition of porcine insulin (0.1 μg/ml) to the incubation medium increases the incorporation of labeled amino acids in the mantle collar in vitro. The immunoblotting technique revealed two immunoreactive insulin bands with a molecular… (More)
