Molluscan gastrin: concentration and molecular forms. 1975

E Straus, and R S Yalow, and H Gainer

Blood and gastrointestinal tissues of the sea hare Aplysia californica and the land snail Otala lactea contain immunoreactive gastrin in heterogeneous forms similar to those of mammals. The observation that blood concentrations in terms of porcine gastrin standard are comparable to those of pig, man, and dog suggests significant homology between the structures of molluscan and mammalian gastrins.
