TransientTransfectionofCos1Cells
Transient Transfection of Cos-1 CellsNote: This protocol has been optimized for Cos-1 cells. Successful transfection of each cell type requires optimization of the basic protocol. Variables to consider for optimization include, but are not limited to, cell density, transfection reagent, duration of transfection, and DNA concentration.1. Seed a six-well tissue culture plate with 1-2 x 105 Cos-1 cells in......阅读全文

细胞转染（Cell－Transfection）技术综述
一、细胞转染途径转染大致可分为物理介导、化学介导和生物介导三类途径。电穿孔法、显微注射和基因枪属于物理介导技术；化学介导方法很多，如经典的磷酸钙共沉淀法、脂质体转染方法、和多种阳离子物质介导的技术；生物介导方法，有较为原始的原生质体转染，和现在比较多见的各种病毒介导的转染技术。1、物理介导（1）电穿

实验概要将转移基因整合到细胞染色体DNA上,形成稳定表达转移基因的细胞系。 实验原理 细胞转染技术是目前广泛应用于病毒基因结构与功能以及基因调控等的研究。细胞转染可分为短暂转染和稳定(或永久) 转染两种。在短暂转染中,被转染基因并不整合至细胞染色体中,因而不能随细胞分裂而传代。转入病毒基因的转
表皮细胞的转染实验技巧
表皮细胞广泛遍布于身体，正常的表皮细胞较难转染，尤其是使用基于脂质体技术的转染试剂。我们使用电转(Amaxa)方法转染正常人的结肠表皮细胞并得到了65%的GFP标记细胞。非常感谢SignaGen,现在我们使用GenJet Ver II可以成功转染正常人的结肠表皮细胞并且转染效率显著提高至75%。

稳定转染的基本概念
一般来说（由细胞类型决定），形成稳定转染细胞的效率比瞬时转染（transient transfection）的效率低1到2个数量级。利用可选择的遗传标记物有利于从非转染细胞的中分离出稀少的稳定转染物。

关于瞬时转染的基本信息介绍
瞬时转染（transient transfection）是将DNA导入真核细胞的方式之一。在瞬时转染中，重组DNA导入感染性强的细胞系以获得目的基因暂时但高水平的表达。转染的DNA不必整合到宿主染色体，可在比稳定转染较短时间内收获转染的细胞，并对溶解产物中目的基因的表达进行检测。
短暂转染的基本概念
中文名称短暂转染英文名称transient transfection定 义外源核酸转染真核细胞后未整合入细胞基因组，而是以附加体形式短时间存在于细胞中，几天后就会丢失的现象。应用学科生物化学与分子生物学（一级学科），方法与技术（二级学科）
