PCRopsis™ Oral Rinse Offers Prolonged Product and Sample Stability While Exhibiting Anti-Microbial Properties and Mediating Direct PCR

Oral samples provide a non-invasive and convenient means of testing people for a variety of medical conditions. In this report we highlight PCRopsis™ Oral Rinse, a device used to collect, transport, and store oral samples for PCR testing. This oral rinse retains its functionality when stored at room temperature for over 6 months. Oral samples collected with this product are stable at 4°C for at least 2 months and at -20°C for at least 5 months. PCRopsis™ Oral Rinse also inhibits ~100% of bacterial growth when mixed 1:1 with saliva, and inhibits ~96% bacterial growth in a 30% oral rinse – 70% saliva mixture when stored at room temperature for 48 hours. This microbial inhibition is observed without the test subject adding a secondary reagent to the sample post sample collection; thereby facilitating sample collection and improving consistency. Moreover, PCRopsis™ Oral Rinse is uniquely compatible with direct PCR approaches that help streamline testing, while reducing costs. As far as we know, there are no other oral sample collection and transport devices that are compatible with direct PCR.
