    Abstract: An expression vector for animal cell is provided to increase expression efficiency of a foreign gene in an animal cell by introducing at least one copy of MAR(matrix attachment region) DNA sequences to the 3' terminal of a gene transcription termination region. An expression vector for animal cell comprises a operatively linked promoter, a polynucleotide encoding a cloning site or a foreign product, and a transcription termination region of which 3' terminal comprises at least two copy of human beta-globin gene MAR DNA sequences in which the MAR sequences are adjacent together or separated by a coding or non-coding sequence. The polynucleotide is LacZ(beta-galactosidase polypeptide), immunoglobulin, GCSF(granulocyte colony stimulating factor) or EPO(erythropoietin) and the animal cell is CHO(Chinese hamster ovary), BHK(baby hamster kidney), NSO(non-secreting mouse myeloma) or human cell.

    Abstract translation: 提供用于动物细胞的表达载体,以通过将至少一个拷贝的MAR(基质附着区)DNA序列引入到基因转录终止区的3'末端来提高外源基因在动物细胞中的表达效率。 用于动物细胞的表达载体包括可操作地连接的启动子,编码克隆位点或外来产物的多核苷酸,以及转录终止区,其3'末端包含至少两个拷贝的人β-珠蛋白基因MAR DNA序列,其中 MAR序列相邻在一起或由编码或非编码序列分开。 多核苷酸是LacZ(β-半乳糖苷酶多肽),免疫球蛋白,GCSF(粒细胞集落刺激因子)或EPO(促红细胞生成素),动物细胞是CHO(中国仓鼠卵巢),BHK(小仓鼠肾),NSO(非分泌型小鼠 骨髓瘤)或人细胞。
