                          Lyophilized from a  0.2 µm filtered  PBS, pH 7.4                          
           
                                                  
            Reconstitution
            We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
           
                    
                    
            Storage Condition
            Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid
              repeated freeze-thaw
              cycles.
           
                              
            Shelf Life
            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. 
           
                    
            Lead Time
            5-10 business days            
           
                    
            Notes
            Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
