目录号:1128
目录编号 包装单位
112801 20
112802 50
适用范围:
适用于快速提取动物细胞和易裂解动物组织总RNA,使用独有基因组DNA清除柱技术确保有效清除gDNA残留,不需要使用DNase消化,RNA可直接用于PCR,荧光定量PCR。

产品介绍:
博凌科为独家推出 HiFi 无苯酚、氯仿RNA快速提取技术基础上,又独家研发成功基因组DNA清除柱技术确保有效清除gDNA残留,得到的RNA不需要DNase消化,可直接用于PCR、荧光定量PCR等实验。独特的裂解液迅速裂解细胞和灭活细胞RNA酶,然后裂解混合物通过一个基因组DNA清除柱,基因组DNA被清除而RNA穿透滤过。滤过的RNA用乙醇调节结合条件后,RNA在高离序盐状态下选择性吸附于离心柱内硅基质膜, 再通过一系列快速的漂洗-离心的步骤, 去蛋白液和漂洗液将细胞代谢物,蛋白等杂质去除, 最后低盐的RNase free H20将纯净RNA从硅基质膜上洗脱。

产品特点:
1.完全不使用有毒的苯酚,氯仿等试剂,也不需要乙醇沉淀等步骤。
2.快速,简捷,单个样品操作一般可在30分钟内完成。
3.独家研发成功基因组DNA清除柱技术确保有效清除gDNA残留,得到的RNA不需要DNase消化,可直接用于PCR、荧光定量PCR等实验。
4.多次柱漂洗确保高纯度,OD260/OD280典型的比值达1.9~2.0,基本无DNA残留,可用于RT-PCR,Northern-blot和各种实验。

The innovative  system is ideal or rapid purification of genomic DNA-free total RNA from animal cells or tissues. The unique genomic DNA elimination columns effectively remove genomic DNA from RNA samples. No DNase digestion step is required. The purified total RNA can be directly used for reverse transcription and RT-PCR. The whole process is phenol/chloroform-free. The unique lysis buffer immediately lyses biological samples and inactivates RNase and DNase. The lysate containing RNA is then passed through a genomic DNA elimination column, where genomic DNA binds to the column membrane, and RNA remains in the flow-through. Ethanol is added to the flow-through to provide appropriate binding conditions for RNA, and RNA selectively binds to the silica-membrane of the RNA column in the high-salt buffer. RNA is purified through a series of wash-spin steps to remove protein followed by elution of RNA from silica-membrane with RNase-free H2O.
