Immunological cross-reactions among cyprinidae parvalbumins

The parvalbumin pattern in white muscle from seven Cyprinidae has been determined by starch gel electrophoresis analysis. The immunochemical discrimination of the various components using several monospecific antisera against a number of distinct Cyprinidae parvalbumins has been qualitatively evaluated by immunoelectrophoresis. The results show that immunologically different groups of parvalbumins can be distinguished within these patterns. One of these groups includes at least one component which is present in each of the seven species investigated. A similar component has been found in a species of Siluridae which, like the Cyprinidae, belongs to the well defined systematic superorder of the Ostariophysi.
