摘要
为探讨应用牛催乳素促进乳腺生物反应器高效表达外源蛋白（如人乳铁蛋白、人血小板生成素）的可行性，构建两种牛催乳素和外源基因乳腺共表达载体。一种为牛催乳素基因和外源基因共用一个6.7 kb山羊β-酪蛋白启动子启动转录，两个基因以内部核糖体进入位点(IRES)连接；另一种为外源基因利用6.7 kb山羊β－酪蛋白启动子，催乳素基因利用2.0 kb山羊β-酪蛋白启动子，分别转录。脂质体转染后，RT...
山羊β乳球蛋白基因的克隆及其在转基因小鼠乳汁中的高效表达Goat β-lactoglobulin Gene Cloning and High Expression in the Mammary Gland of Transgenic Mice
