CO2恒温摇床解决人胚肾－293－(HEK293)－细胞结团问题（一）
人胚肾 293 (HEK293) 细胞在重组蛋白表达中是最常见的宿主细胞。 这类细胞能够表达大量的膜蛋白，如 G 蛋白偶联受体 (GPCR) ，是无法在最常见的生物制药生产宿主，如：中国仓鼠卵巢 (CHO) 细胞中作表达。 HEK293 虽然是蛋白表达的极好宿主，然而 HEK293 细胞
重组质粒（dna－recombinant－plasmid）的连接、转化及筛选2
第二节 材料、设备及试剂一、 材料外源DNA 片段: 自行制备的带限制性末端的DNA 溶液,浓度已知; 载体DNA : pBS质粒(Ampr ,lacZ),自行提取纯化,浓度已知; 宿主菌: E. coli DH5α,或JM系列等具有α-互补能力的菌株。二、 设备恒温摇床，台式高速离心机，恒温水浴锅
重组质粒（dna－recombinant－plasmid）的连接、转化及筛选1
第一节 概 述质粒具有稳定可靠和操作简便的优点。如果要克隆 较小的DNA 片段(＜10kb)且结构简单,质粒要比其它任何载体都要好。在质粒载体上进行克隆 ,从原理上说是很简单的，先用限制性内切酶切割质粒DNA 和目的DNA 片段, 然后体外使两者相连接, 再用所得到重组质粒转化细菌,即可完成
