Zusammenfassung:	L'invention concerne une substance exempte de mitogène, présentant des polymères mixtes de 10 à 90 % molaire d'acide guluronique complété à 100 % par de l'acide mannuronique, d'un poids moléculaire compris entre 10 000 et 500 000 dalton. L'invention concerne également un procédé de fabrication de cette substance et son application. PCT No. PCT/DE93/00136 Sec. 371 Date Aug. 10, 1994 Sec. 102(e) Date Aug. 10, 1994 PCT Filed Feb. 12, 1993 PCT Pub. No. WO93/16111 PCT Pub. Date Aug. 19, 1993Proposed is a mitogen-free substance comprising cross-linked copolymers including 10 to 90 mole % of guluronic acid, the balance being made up of mannuronic acid. The substance has a molecular weight of from 10,000 to 500,000 Daltons. Also proposed are methods for preparing such substances and their use.
