Collect superior samples for your genetic analysis

All genetic research starts with the collection of DNA samples. Collect reliable samples with an all-in-one system for the collection, stabilization and transportation of DNA from saliva.

  • Non-invasive, reliable self-collection that increases compliance and decreases costs
  • DNA from saliva is equivalent to DNA from blood for downstream applications
  • Sample remains stable for years at room temperature, reducing transportation and storage costs
  • Sample can be mailed using the standard postal system
  • Ideal for use with children or donors that will not comply with blood collections
