Extract high quality & quantity total RNA including miRNA Isolate from a wide variety of animal tissues No phenol step required - isolate all RNA in one fraction Compatible with tissues stored in RNAlater® or Trizol® Convenient & fast spin column format Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix This kit is suitable for the isolation of total RNA from a range of animal tissues such as liver and spleen, as well as difficult fibrous tissues such as heart, muscle, intestine, etc. Briefly, the tissue of interest is first lysed using Buffer RL, followed by treatment with the provided Proteinase K which aids in the removal of the various proteins present in fiber-rich tissues including collagen, contractile proteins, and connective tissues. The purified RNA is of the highest quality and purity, with excellent RIN values and A260/A280, and is 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.
