Abstract

Parvalbumins, calcium-binding, heat-stable proteins of considerable allergenic potential, are occurring in high concentration in light muscle of many fish species. Lack of knowledge about parvalbumins in sturgeon tissues prompted us to study the distribution of this type of proteins in light and dark muscle, as well as in swim bladder and skin of Atlantic sturgeon, Acipenser oxyrhynchus, and three other sturgeon species. Results: Light and dark muscle of sturgeons contained water soluble proteins with following properties: (1) Great stability against heating at 70 or 80 °C. (2) Isolelectric points between 3.85 and 5.66. (3) Treatment of proteins separated by isoelectric focusing with the dye “stains all” gave blue protein bands. (4) The molecular mass was about 10 to 14 kDalton. (5) Concentration of acidic, heat-stable proteins was higher in light than in dark muscle. Taken together, these findings gave strong indication for the presence of parvalbumins in muscle tissue of sturgeons. This conclusion was corroborated by immunological tests. However, parvalbumin could not be detected in swim bladder tissue. Skin preparations showed only traces of parvalbumins, possibly resulting from residual muscle tissue.
