METHODS摘要: Molecular cloning techniques were used to construct the recombinant plasmid pLMP1p53mt containing mutant p53 gene and EB virus LMP1 gene. Linear recombinant plasmid pLMP1p53mt was transfected into mouse androgenesis of germ cells by microinjection and then survival germ cells treated were planted into fallopian tubes of artificial pregnant female mice.

方法摘要：通过分子克隆技术构建含突变型p53基因和EB病毒LMP1基因的真核表达载体pLMP1p53mt；采用显微注射法将线性化的表达载体注射至小鼠受精卵的雄性原核中，然后将注射存活的受精卵植入假孕母鼠的输卵管；取其产3 wk龄子代鼠进行PCR初选，再通过Southern杂交进一步确证；利用HE染色法观察4 mo龄转基因小鼠不同组织病理变化。
