摘要: 试验以南美白对虾、刀额新对虾、罗氏沼虾为研究对象,利用单向SDS-PAGE凝胶电泳和双向电泳技术建立3种虾类的电泳图谱,建立分辨率高、重复性好的虾肉双向电泳图谱,并进行差异分析。结果表明:比较3种虾类蛋白图谱,发现具有统计学意义和分析意义的差异蛋白点共37个,其中15个蛋白点为南美白对虾的特征蛋白点,而刀额新对虾与罗氏沼虾的特征蛋白点分别为3个,7个。

Abstract: Using Penaeus vannamei, Metapenaeus ensis and Macrobrachium rosenbergii as materials, the shrimp meat electrophoretic patterns with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and two-dimensional gel electrophoresis (2-DE) which showed high resolution and good repetition was established. The comparison study was conducted to analyze the differentially expressed proteins among three breeds. The result indicated that 37 spots showed a significant difference among three shrimp species by using statistical and quantity analysis. The 2-DE maps of Penaeus vannamei, Metapenaeus ensis and Macrobrachium rosenbergii meats demonstrated 15,3,7 spots respectively as characteristic protein spots.
