  • Process for extraction of a growth factor complex
    Patent number: 6177550
    Abstract: The process of the invention for the extraction of a Growth Factor Complex is characterized in that water is added to natural and growth factors containing material, the pH value is adjusted to 2.5 to 3.2 by the addition of acid, the resulting precipitate is separated from the supernatant, the Growth Factor Complex in the aqueous solution is precipitated by the addition of an organic solvent miscible with water, separated from the liquid phase and dried, and the powder obtained is, if desired, dialyzed.
