摘    要:对细菌纤维素产生菌株———葡糖酸醋杆菌菌体蛋白的提取过程、等电点的分布及纯化方法等方面进行了探索和优化。结果表明:葡糖酸醋杆菌蛋白主要分布在pI 4~7的范围内;采用超滤浓缩后进行2D Clean-up试剂盒纯化,可以获得更优的蛋白分离效果;在考马斯亮蓝G250染色条件下,有效分离出(1037±65)个蛋白点;建立了高质量葡糖酸醋杆菌蛋白的双向凝胶电泳分析技术。

关 键 词:细菌纤维素  欧罗巴葡糖酸醋杆菌  双向电泳  蛋白质组学

Abstract:The protein extraction,isoelectric point of distribution and protein purification of the proteins of Gluconacetobacter,a stain produced bacterial cellulose,were tried and optimized to establish a set of two-dimensional polyacrylamide gel electrophoresis (2DE) techniques for proteomic analysis of Gluconacetobacter.The results showed that Gluconacetobacter proteins were mainly distributed in the range of pI 4-7.The 2D Clean-up kit purification after ultrafiltration concentration gave better protein separation effect.Under Coomassie brilliant blue G250 condition,(1037 ±65) protein points were isolated.
Keywords:Gluconacetobacter  two-dimensional polyacrylamide gel electrophoresis  proteomics
