DNA体外转染试剂_如何准备转染所需的质粒DNA
转染效率受到诸多因素的影响，除了细胞、培养基和载体等影响因素外，另外一项非常重要的因素便是DNA的质量。为了比较不同厂家的转染效率，我们分别从三家不同的供应商购买了质粒制备试剂盒来制备pEGFP-N3质粒DNA，并通过不同的方法将制备的pEGFP-N3质粒转运至NIH-3T3细胞。pEGFP-N3质

定位候选克隆
当前，人类基因组研究的重心正在由“结构”向“功能”转移，一个以基因组功能研究为主要内容的所谓“后基因组时代”(post-genomics)，也即功能基因组(functional genomics)时代，即将到来。如何获取基因的功能信息，即与人类重大疾病和重要生理功能相关的基因信息，就摆在了我们面前。
