焦磷酸测序(Pyrosequencing)技术是新一代DNA序列分析技术,该技术无须进行电泳,DNA片段也无须荧光标记,操作极为简便。
The Spliceosome Dance(剪切子的模拟动画)
This protocol adapts the method of Williams and Bartel (Nucleic Acids Res. 23:4220) to generate single-stranded DNA suitable to go directly into the emulsion PCR step of 454 pyrosequencing. The protocol was first performed by Wendy Johnston (Bartel lab).
毛细管电泳(capillary electrophoresis CE)又叫高效毛细管电泳(HPCE) 是近年来发展最快的分析方法之一。1981年Jorgenson和Lukacs首先提出在75μm内径毛细管柱内用高电压进行分离 创立了现代毛细管电泳。1984年Terabe等建立了胶束毛细管电动力学色谱。1987年Hjerten 建立了毛细管等电聚焦 Cohen和Karger提出了毛细管凝胶电泳 ...
毛细管电泳技术(Capillary Electrophoresis CE)又称高效毛细管电泳(HPCE)或毛细管分离法(CESM),毛细管电泳方法虽新工艺,但历史悠久,它是在电泳技术的基础上发展的一种分离技术。电泳作为一种技术出现,已有近百年的历史,但真正被视为一种在生物化学中有重要意义的技术,是由1937年A. Tiselius 首先提出。传统电泳最大的局限是难以克服由高电压引起的焦耳热,196 ...

掌握双脱氧链终止法测定DNA序列的原理与方法 DNA聚合酶催化的DNA链延伸是在3’-OH末端上进行的。由于2’,3’-双脱氧三磷酸核苷酸(ddNTP)的3’-位脱氧而失去游离-OH,当它参入到DNA链后,3’-OH末端消失,使DNA链的延伸终止。 本实验根据此原理,将待测DNA片段插入单链噬菌体M13载体,并用合成的寡聚核苷酸引物 ...

在分子生物学研究中,DNA 的序列分析是进一步研究和改造目的基因的基础。目前用于测序的技术主要有Sanger等(1977)发明的双脱氧链末端终止法和Maxam和 Gilbert(1977)发明的化学降解法。这二种方法在原理上差异很大,但都是根据核苷酸在某一固定的点开始,随机在某一个特定的碱基处终止,产生A,T,C,G四组不同长度的一系列核苷酸,然后在尿素变性的PAGE胶上电泳进行检测,从而获得DN ...
