I never tried myself either hehe. theoretically, there is a kd involved (though it's very very low) so you can compete the DNA off. or some harsh condition (heat, NaOH, etc) may elute the DNA off. don't know whether you can still use the beads after that thou hehe
I agree:) the half-life should be ~10days, so if you add 100X excessive biotin you might be able to recover your DNA after a month? hehe but I thought PCR should be good? remember reading somewhere ppl use heating for elution. anyway, probably not worth it (though I'm indeed curious:)
I tried gel extraction kit w/ 10ug+ DNA and worked fine. I tried even higher amount w/ YM columns and got great recovery. they can be reused too. but don't know whether that's compatible w/ gel extraction buffer
