Can I remove an aliquot of recovered DNA and “redry” the sample?
Yes, if you rehydrated your sample in 20µl, simply rehydrate an unused GenTegra™ DNA Tube in 20µl of hydration solution and add the rehydrated GenTegra™ matrix to your sample to bring the volume up to 20µl. Dry the sample according to the protocol in the GenTegra™ DNA user manual. This ensures that the sample retains the optimal concentration of GenTegra™ matrix. If you rehydrated your sample in a volume other than 20 µl, rehydrate the unused GenTegra™ DNA Tube in the same volume. For best results, redry the sample and discard the rehydrated GenTegra™ matrix within 24 hr of recovery.
