Vaccinia virus (strain Western Reserve) (VACV) (Vaccinia virus (strain WR))
Serine proteinase inhibitor 3
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.
Prevents cell to cell fusion via its interaction with A56 protein. The A56-K2 complex associates with components of the entry fusion complex (EFC) presumably to avoid superinfection and syncytium formation.
