What Scientists are Saying About this Product


Stool Total RNA Purification Kit

Cat. 49500

A convenient and rapid method to purify total RNA from small amounts of stool samples.

  • Simultaneous isolation of both host RNA and microbial RNA (universal protocol)
  • Isolate full diversity of RNA from large RNA down to small and microRNAs
  • Eliminates PCR inhibitors including humic acids
  • High quality RNA for sensitive downstream application
  • Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

For research use only and NOT intended for in vitro diagnostics.

Stool Total RNA Purification Kit

This kit provides a convenient and rapid method to purify total RNA from small amounts of stool samples. All types of stool samples can be processed with this kit, including animal fecal samples, manure and samples collected using Norgen's Stool Nucleic Acid Collection and Preservation Tubes (Cat. 45660). The kit removes all traces of humic acids using rapid and simple spin column procedures. Bead tubes are also provided for effective homogenization of stool. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA and small interfering RNA. Both host and microbial RNA is recovered. The protocol does not rely on the use of phenol or chloroform, thereby providing a user friendly procedure and allowing high-throughput analysis. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR and reverse transcription PCR for gene expression analysis. The procedure can be completed in approximately 30 minutes for 10 samples.
