Urokinase manufacturer: Detection of Urokinase activity [kangyuan]

　　As a thrombolytic drug for thrombus patients, urokinase is currently not available as an alternative drug, and there is a serious shortage of urokinase in the pharmaceutical market, so it has attracted the attention of the media and the public. The current urokinase extraction process, about a ton of urine can extract 120-150g of urokinase, urokinase technology is not very difficult, there are mainly the following three extraction methods
