外源基因导入原核和真核细胞技术是重组DNA在细胞中表达所不可缺少的手段之一。本实验采用已构建的嵌合基因(小鼠Ig可变区基因已连接在人Ig恒定区基因上)pSVΔHgpt17-1A-V_(11)hCr_3(pSVgpt-r_3)和pSV _(134)ΔH meo DNS V_k H_uK(pSV meo-K)(美
Introduction of exogenous genes into prokaryotic and eukaryotic cells is one of the indispensable means of recombinant DNA expression in cells. In this study, pSVΔHgpt17-1A-V (11) hCr_3 (pSVgpt-r_3) and pSV_ (134) ΔH meo DNS were constructed using the constructed chimeric gene (the mouse Ig variable region gene has been linked to the human Ig constant region gene) V_k H_uK (pSV meo-K) (United States
