                                    | Endotoxin : | Less than 1.0 EU per μg by the LAL method. | 
                                
                                    | Purity : | >90% as determined by SDS-PAGE. | 
                                
                                    | Storage : | For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after  at: -20°C to -70°C for 12 months in lyophilized state;  -70°C for 3 months under sterile conditions after reconstitution.
