Abstract
The construction and analysis of bacterial plasmids that contain and phenotypically express a mammalian genetic sequence are described. Such plasmids specify a protein that has enzymatic properties, immunological reactivity and molecular size characteristic of the mouse dihydrofolate reductase, and render host cells resistant to the antimetabolic drug trimethoprim.
摘要
本文描述了含有哺乳动物基因序列并能表型表达该序列的细菌质粒的构建与分析。此类质粒可编码一种具有酶活性、免疫反应性以及小鼠二氢叶酸还原酶分子大小特征的蛋白质，并使宿主细胞对抗代谢药物甲氧苄啶产生抗性。
