because peg reagents are temperature, light, and moisture sensitive they should be stored in a -15℃ freezer upon receipt. please allow peg reagents to equal room temperature prior to opening. we recommend storing our peg reagents as the dry, powder form only and not in any type of solution.  each time the bottle is opened it will need to be backfilled with an inert gas (i.e. argon,nitrogen) before it is stored again.  if your reagent requires rebottling please follow these steps:

      a) allow reagent to equilibrate to room temperature

      b) while reagent is thawing prepare glove box or another suitable area for packaging which will allow for an inert atmosphere

      c) flush the repackaging enclosure with an inert gas (i.e. argon, nitrogen)

      d) repackage into desire aliquots

      e) flush each aliquot with inert gas before closing

      f) store each aliquot at or below -15℃ until ready to use
