  • Process for production of fibrinogen and fibrinogen produced thereby
    Patent number: 11401300
    Abstract: A process for purifying fibrinogen from a fibrinogen containing source by precipitation of fibrinogen by a precipitating agent from a fibrinogen containing solution in the presence of one or more chelating agent(s) and removal of the supernatant from the fibrinogen paste, characterised in that fibrinogen is extracted from the paste forming a liquid fraction containing fibrinogen, and an undissolved residue, which is separated from the liquid.
