填补Qiagen空白、不用DNA酶消化的植物RNA提取试剂盒 一般公司多糖多酚植物RNA提取试剂盒失败原因和解决方案 很多植物RNA的样品由于含有大量的多糖、多酚、代谢产物、色素等成分,造成RNA提取过程中氧化、褐化、降解、由于植物品种的多样性造成情况更加复杂。手工的CTAB类的方法提取因为时间太长,太繁琐,手工方法不在讨论之列。一直以来没有一款好的试剂盒包括qiagen、promega等进口试剂 ...
产品技术背景pRI系列载体是基于III类RNA聚合酶启动子:人类H1启动子的专用于哺乳动物细胞RNA干扰的载体。H1启动子在哺乳动物细胞内合成类似siRNA分子的小分子RNA。由于H1启动子有精确的转录起始位点和终止信号,H1启动子转录产物精确生成人工设计的shRNA,shRNA经过RISC剪切后形成有2个U突出末端的成熟siRNA。由于H1启动子对转录产物长度的严格限制,基本上杜绝了非特异性干 ...
