title: Protectins in Argentine mollusks: immunological and immunochemical aspects.
abstract: Protectins and agglutinins in several organs, fluids and spawn from Argentine terrestrial and fresh-water gastropod species were examined. Differences or analogies with vertebrate immunoglobulin serological behaviour are summarized. Individual or group variability and the evolutionary meaning of the reproductive system-linked and the Ca++ ion-linked protectins are discussed.
