CONSTITUENTS OF UNIONID EXTRAPALLIAL FLUID. I. ELECTROPHORETIC AND IMMUNOLOGICAL STUDIES OF PROTEIN COMPONENTS

Abstract
Components of extrapallial fluid of several species within the three sub-families of the family Unionidae have been comparatively analyzed. It has been found that the proteins involved in shell formation for these species are strikingly similar, electrophoretically and immunologically. These data infer that the same protein components may well be involved in the formation of shell within species of the family Unionidae.
