All proteins are accompanied by product information sheets which describe proper storage conditions. Many of our preparations are formulated in 50 % (vol/vol) glycerol/H₂O which will remain in fluid phase during storage at -20° C.
This preferred method of storage yields the greatest stability while still allowing access to the stock sample without repeated thawing and freezing steps.
All products which are formulated with glycerol/H₂O should be stored at -20° C.
Temperatures lower than -30° C should be avoided in order to prevent a phase transition.
When preparing to make a dilution of the stock sample, remove the sample from storage at -20° C and place on ice for a brief period of time (5-10 min).
The sample will become less viscous and thus easier to pipe. Never allow protein solutions to remain at room temperature for excessive periods of time.
