storage: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 months at -20℃,-80℃. Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
background:Initiates blood coagulation by forming a complex with circulating factor VII or VIIa. The [TF:VIIa] complex activates factors IX or X by specific limited protolysis. TF plays a role in normal hostasis by initiating the cell-surface assbly and propagation of the coagulation protease cascade.
