"By using HOMIM (Human Oral Microbe Identification Microarray), we demonstrated that saliva samples stored in OMNIgene•ORAL were indeed stabilized for at least 3 weeks, even at 37° Celsius. This is outstanding! Consequently, I think OMNIgene•ORAL would be very useful for remote collections alleviating the need for a -80° freezer or, for that matter, any refrigeration to preserve samples. This is an incredible benefit for any investigator who is interested in preserving precious clinical samples, especially for use with molecular analyses of genomic material."

OMNIgene•ORAL (OM-505)

All-in-one system for the collection and rapid stabilization of microbial nucleic acids

Microarrays and Next Generation Sequencing give researchers the ability to easily detect and quantitate molecular targets in a highly multiplexed fashion. Due to the complex nature of samples required for metagenomic research of the microbiome, bias can be easily introduced through improper sample collection, stabilization and transport.

  • Provides a snapshot of the microbial profile at time of collection and prevents microbial growth
  • Stabilizes RNA at room temperature and DNA up to 37°C for 3 weeks
  • Easy self-collection of high quality DNA and RNA from oral samples
  • Eliminates the need for cold chain transportation
  • Compatible with downstream applications (e.g., RT-qPCR, microarray)

Complete donor user instructions for this product are available here.


  • Stabilizes samples at point of collection ensuring the DNA and RNA is unchanged at time of processing
  • Facilitates simultaneous detection of DNA and RNA from bacteria and viruses all from one sample
  • Reduces transportation and storage cost and complexity with 3 weeks of ambient temperature stability of DNA and RNA
  • Enables identification of the living or metabolically active bacteria at time of collection through RNA expression profiling
  • Format compatible with high-throughput processing increases efficiency and minimizes sample handling errors
