The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 mo
Notes:
Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.
