Urokinase manufacturer: Urokinase extraction method

  Urokinase, as a thrombolytic drug for patients with thrombosis, currently has no suitable alternatives, and there is a serious shortage of Urokinase in the pharmaceutical market, so it has attracted the attention of the media and the public. In the current Urokinase extraction process, about one ton of urine can extract 120-150g of Urokinase, the technical difficulty is not high, there are mainly three extraction methods as follows.

  1. Precipitation method: use a precipitating agent, put the agent into the urine, and finally precipitate the crude Urokinase.

  2. Soaking method: First, stir the urine at a high speed, add ammonium sulfate after stirring the foam, and get the crude Urokinase Precipitant method: The precipitation method is to add a precipitant to the urine to precipitate Urokinase.
