Protein samples stored at -80ºC will be frozen. As repeated freeze-thaw cycles usually have a negative influence on protein samples, it is best to prepare small-sized, single-use aliquots that will be used up during the course of an experiment. 5-10% glycerol or other additives that protect against the effect of freezing and thawing can be added as well. After preparing your protein sample aliquots, it is important to flash-freeze them in liquid nitrogen before importing them into the -80ºC freezer for long-term storage. Many proteins are stable for months to years when stored under appropriate conditions at -80°C, but the exact time frame varies from protein to protein and should be determined experimentally.
