文献和实验Sequence-specific electron injection into DNA from an intermolecular electron donor.
Electron transfer in DNA has been intensively studied to elucidate its biological roles and for applications in bottom-up DNA nanotechnology. Recently, mechanisms of electron transfer to DNA have been investigated; however, most of the systems designed are intramolecular. Here, we synthesized pyrene-conjugated pyrrole-imidazole polyamides (PPIs) to achieve sequence-specific electron injection into DNA in an intermolecular fashion. Electron injection from PPIs into DNA was detected using 5-bromouracil as an electron acceptor. Twelve different 5-bromouracil-containing oligomers were synthesized to examine the electron-injection ability of PPI. Product analysis demonstrated that the electron transfer from PPIs was localized in a range of 8 bp from the binding site of the PPIs. These results demonstrate that PPIs can be a useful tool for sequence-specific electron injection.
一般-20度保存半年应该没问题 DMSO是无菌的啊 chenfengyiguo 关于PMA溶解分装的帖子好多,据我所知的包括园里和文献,有以下需要解决的问题: 1:PMA作为一种PKC激动剂,常用于THP-1或者U937细胞的诱导为巨噬细胞。分子量616.8 2:一般是买sigma的,1mg包装,使用浓度有100nm/L~160nm/L(指上述细胞),那么1mg可处理10L细胞(160nm/L),故一般买1mg包装就足够
10分钟后,分装成小份(1 ml/份)。-20℃保存。 9. 使用前在沸水浴中加热5分钟后,迅速冰浴冷却。 sigma D1626 脱氧核糖核酸DNA 购买链接: http://www.biobars.cn/shop/goods.php?id=1665 (责任编辑:大汉昆仑王)
尿嘧啶糖苷酶的表达与纯化 做完taq酶的表达与纯化接着就做ung酶的表达与纯化,虽然刚刚做完taq酶的表达,但还是花了两个星期才做好ung酶的表达与纯化,把实验中的心得写出来,希望对大家有所帮助。 1:蛋白表达的实验前准备,确认原材料的来源与实验用水的洁净度,认真的配好每一种试剂,设计好实验方案。 2:上NCBI查找基因序列,确认ung酶基因在大肠杆菌K12菌株基因组的58.4min。总长度为690bp,所表达蛋白大小为25.69K道尔顿。 相关网址: http://ecoli
