Urokinase Human
Catalogue Number ENZ-264
Synonyms Urokinase, Abbokinase, Urokinase-type Plasminogen Activator,uPA, EC, UK.
Introduction Urokinase (UK) is a serine protease, which is one of biological plasminogen activators.
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.
Description Urokinase is a two-chain glycoprotein containing 411 amino acids with 12 disulfide bonds. Its molecular weight is 54,000 Dalton.
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 although 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 94.0% as determined by SDS-PAGE.
Specific Activity 174,827IU/mg.
Contaminants Free of: Hepatitis B surface antigen, Hepatitis C antibody and HIV I and II.
