It is involved in a number of biological functions including fibrinolysis, embryogenesis, cell migration, tissue remodeling, ovulation, and wound healing. It can be obtained from human urine or kidney cell culture. | 
| Synonyms | Urokinase, Abbokinase, Urokinase-type Plasminogen Activator,uPA, EC 3.4.21.73, UK. | 
| Source | Human urine. | 
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | 
| Formulation | The Urokinase was lyophilized from a concentrated (1mg/ml) solution containing phosphate buffer. | 
| Solubility | It is recommended to reconstitute the lyophilized Urokinase in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | 
| Stability | Lyophilized Urokinase althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Urokinase should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles. | 
| Purity | Greater than 92.0% as determined by SDS-PAGE. | 
| Usage | NeoBiolab's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drµgs, agricultural or pesticidal products, food additives or household chemicals. |
