[DIYbio] Re: How to archive (long and precious) DNA samples for (potentially) long time?

Hi colleagues,

I split this question off into a separate thread for legibility...

Please, what way of preservation would you choose for DNA samples, provided that they are (all three):

* precious (hard or even impossible to recollect when lost)

* possibly very long (including whole human/mammalian genomes)

* needed to be stored for long time (years or tens of years)

(More specifically, I'm trying to save the genome of a talented person precious to me, with hope that, in case of a disastrous event, the specific talents and potential will not be lost completely. Feel free to call me naive...)

I suspect the normal ice won't be enough here. Intuitively I would choose storing it in deep freeze in rare gas, but that needs a constant supply of energy, which is expensive and inconvenient.

Any idea of another technique? Suspending in some kind of resin, maybe?

Thanks in advance for any ideas.
