For rapid purification of total RNA - including microRNA - without phenol

  • Extract high quality & purity total RNA including miRNA
  • No phenol step required
  • Bind & elute all RNA irrespective of size or GC content, without bias
  • Efficiently extract small RNA irrespective of GC content
  • Very sensitive & linear down to a few cells without the need for carrier RNA
  • Convenient & fast spin column format
  • Isolate from a wide variety of specimens


This kit is suitable for the isolation of total RNA from a range of samples including cells, bacteria, yeast, virus and bodily fluids including plasma/serum, blood, saliva, CSF and more. Extract high quality and purity RNA with excellent RIN values and A260/A280 suitable for downstream applications including qRT-PCR, RT-PCR, microarrays, NGS and more.

The kit purifies all sizes of RNA from large mRNA, lncRNA down to microRNA (miRNA) in the same fraction without the requirement of phenol. Isolate all RNA sequences at an equal rate irrespective of size. Moreover, when the RNA sequences are small (e.g. miRNA), the column binds small RNAs regardless of their GC content.
