You can collect – stabilize – concentrate – transport – extract – and store: All of this functionality in a single DNA collection tube. Collected samples are stable at room temperature for 5+ years. They also have a high genomic DNA Yield (10-30 µg avg.), extremely low bacterial contamination (<1%), and the non-alcoholic buffer requires no Hazmat fee when shipping back to the lab. This collection tube requires 4 buccal swabs (sold separately).
