| 摘 要： | 运用水油提、盐析及凝胶过滤色谱法对幽门螺杆菌ＹＣ－１１株所分泌的形成空泡细胞毒素进行了提取。纯化的形成空泡细胞毒素在ＳＤＳ－聚丙烯酰胺凝胶电泳中表现为单一条带，分子量约为８７０００，在ＰＨ２．４～６．４的环境中表现高细胞毒性。 |
| 关 键 词： | 幽门螺杆菌，形成空泡细胞毒素，提纯 |

| Abstract: | The vacuolating Cytotoxin from Helicobacter pylori YC-11 was purified by using water-extracting,salt precipitation and gel filtration chromatographic fractionation.The purified vacuolating cytotoxin showed a single band on SDS-PAGE,and its molecular weight was about 87000.Within pH 2.4-pH 6.4 a higher cytotoxicity existed. |
| Keywords: | Helicobacter pylori:vacuolating cytotoxin purification |
