Description
Urokinase is a two-chain glycoprotein containing 411 amino acids with 12 disulfide bonds. Its molecular weight is 54,000 Dalton.
The Urokinase was lyophilized from a concentrated (1mg/ml) solution containing phosphate buffer.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
Greater than 90.0% as determined by SDS-PAGE.
Solubility
It is recommended to reconstitute the lyophilized Urokinase in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Source
Human urine.
Specific Activity
83,700IU/mg.
Stability
Lyophilized Urokinase although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution Urokinase should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
Please prevent freeze-thaw cycles.
