    • A modified transposon vector and a method for introducing a foreign gene into a cell are provided. A modified transposon vector wherein a nucleic acid fragment having the following features (a)-(b) or (a)-(c) is inserted; a cell expressing a foreign gene obtained by introducing said vector into chromosomal DNA of a cell line or an ontogenetic cell and further introducing an expression cassette of a foreign gene into the chromosomal DNA; a genetically recombined animal generated by using said cell (in case of an ontogenetic cell); and a method for producing a foreign protein from said cell and said genetically recombined animal: (a) It consists of 5′- and 3′-TIR sequences of a transposon gene; (b) A sequence where a recombination reaction occurs is inserted between at least either of DR regions present by twos each in 5′- and 3′-TIR sequences of a transposon gene; (c) A restriction enzyme recognition site or an expression cassette of a foreign gene is inserted between 5′- and 3′-TIR sequences of a transposon gene.
    • 提供了修饰的转座子载体和将外源基因导入细胞的方法。 其中插入具有以下特征(a) - (b)或(a) - (c)的核酸片段的修饰的转座子载体; 通过将所述载体导入细胞系或本体细胞的染色体DNA而获得的表达外源基因的细胞,并进一步将外源基因的表达盒导入染色体DNA; 通过使用所述细胞产生的遗传重组的动物(在个体发生细胞的情况下); 以及从所述细胞和所述遗传重组动物产生外源蛋白的方法:(a)其由转座子基因的5'和3'-TIR序列组成; (b)将重组反应发生的序列插入转座子基因的5'-和3-TIR序列中的两个存在的至少任一个DR区域; (c)将外来基因的限制性内切酶识别位点或表达盒插入转座子基因的5'和3'-TIR序列之间。
