Human adenovirus B serotype 7 (HAdV-7) (Human adenovirus 7)
Early E3 20.5 kDa glycoprotein
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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
E3 proteins seem to be dispensable for virus growth in tissue culture cells. They are potentially important for virus growth under special conditions; E3 region may help adenoviruses to evade the immune surveillance of the host.
