Extraction method of Urokinase manufacturer
Urokinase is extracted from urine. This article introduces several
extraction methods in the production process of crude Urokinase:
Urokinase method/step
Precipitation method: using a precipitant, put the precipitant into the
urine to precipitate Urokinase.
Foaming method: The foaming method requires rapid stirring of the urine
with a machine to make it foam, and then liquefies the foam and then adds
ammonium sulfate (NH₄)₂SO₄ to precipitate Urokinase to obtain a crude
product.
Adsorption method: The adsorption method is to add an "adsorbent" to the
urine to absorb the crude Urokinase. At present, the adsorption method is the
most widely used in the Urokinase extraction process. Adsorbents include resin
adsorption and diatomaceous earth adsorption two processes
