摘要：

Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and isoelectric focusing (IEF) analyses of caviar were used to identify species of American, European and Asian sturgeon. Caviar samples of American and Gulf of Mexico sturgeon showed distinctive protein banding patterns on SDS-PAGE. IEF gels containing 20% pH 3-10 and 80% pH 4-6.5 ampholyte enabled differentiation of sturgeon species. IEF was more reliable than SDS-PAGE for identification of sturgeon species.
