Hello!
I am using DNeasy PowerBiofilm Kit to isolate DNA from skin swabs. Now I am considering if I should use the provided collection tubes to final storage of extracted DNA. DNA can bind to plastic walls of the tube, so should I rather use low-DNA binding tubes from Eppendorf? On the other hand, the kit has been made for the extraction of DNA from various types of source samples, so it should be appropriate for DNA storage, despite nowhere is wrote that the tubes are DNA-low binding?
Any suggestions?

In theory the kit tubes should be fine. You may want to use screw cap tubes if you want to transport your DNA samples any distance though.
The kit tubes should be fine for short-term storage. If you want to freeze the samples for longer, I'd recommend transferring to "cryo vials" with the screw top & gasket seal. Prevents evaporative loss in storage. Not that the DNA would evaporate, but it means the concentration will change and total loss of water can damage the DNA.
In my opinion, kit tubes should be fine. If adherence is the problem, you can short-spin it after adequate tap mixing.
Hope, it helps.
