RNA Isolation or Purification—Mini Spin Columns

NucleoSpin RNA is recommended for isolation and purification of total RNA from cultured cells, tissue, bacteria, yeast, cell-free biological fluids, and reaction mixtures without the use of organic compounds (e.g., Trizol). This kit allows purification of up to 70 µg of highly pure, DNA-free total RNA.

Total RNA prepared with NucleoSpin RNA is suitable for applications such as reverse transcriptase-PCR (qRT-PCR), Northern blotting, primer extension, array technology, and RNase protection assays. For isolation of high-quality RNA, it is important to prevent degradation of the RNA and to eliminate genomic DNA. With the NucleoSpin RNA method, cells are lysed in the presence of chaotropic salts. The lysis buffer immediately inactivates RNases, which are present in virtually any biological material, and creates appropriate conditions for RNA to bind to the silica membrane. After lysis, homogenization and reduction of viscosity are achieved by filtration with NucleoSpin Filter units (shredders), which are provided with the kit. Residual genomic DNA is efficiently removed by on-column digestion with rDNase, which is also included in the kit.
