Oragene•DISCOVER (OGR-575)
for Assisted Collection

Collect superior samples for your genetic analysis

Are you looking for a non-invasive way to collect DNA from patients that cannot or choose not to comply with blood collections? DNA Genotek has developed a product for collecting high quantity and high quality DNA from saliva using absorbent sponges. This method is an all-in-one system for the collection, stabilization and transportation of DNA from saliva.

  • Non-invasive, reliable collection that increases compliance and decreases costs
  • Eliminate phlebotomy costs and requirement for a clinic/hospital setting
  • DNA from saliva is equivalent to DNA from blood for downstream applications
  • Ideal for use with children or donors that are not able to spit
  • Sample remains stable for years at room temperature, reducing transportation and storage costs
  • Sample can be mailed using the standard postal system
  • Increase efficiency, minimize sample handling and reduce handling errors with a compatible format for high-throughput processing
