DNA attachment to tubes

[samkh918]

Hello,

I use QIAGEN Plasmid Maxi kit to extract plasmid DNA from bacterial cells. In the final steps of the procedure I have to use a 30ml tube to elute the DNA with 15ml of buffer and then add 10.5ml of isopropanol to it to precipitate the DNA. Should I use plastic Flacon tubes or Glass tubes? I want the one with less DNA attachments to the tube so that I minimize the loss of DNA? Does DNA attach more to plastic or glass?!

Thanks for your help.

Does DNA attach more to plastic or glass?!

Just a guess mind you, but I would think glass would have less bonding, based on the crystal lattice structure of Si (Si in lattice form is stable). Like I said though, just a guess.
