Great pics and discussion but one "not" was missing, I think, somewhere after "Unfortunately".

Took a look at your experimental conditions (on the whiteboard pic), and noticed you guys are using combinations of glycerol/DMSO/glycol in your different test solutions. Just wondering if you guys are also trying recombinant approaches, for example E. coli strains engineered (possibly by genomic integration) to express antifreeze proteins:


That might be an interesting project -- a DIY-engineered E.coli strain that is amenable to storage at -20C for prolonged times, that can be distributed to DIYbio communities globally.

Also, trehalose has been shown to be superior to DMSO or glycerol for cryostorage of cells:

In addition, trehalose is dirt cheap, much cheaper than glycerol or DMSO; it goes for about $5-10 per pound:

does this mean the experiment will be repeated? I'm back in town for a few weeks and eager to get involved.
