Publication number: 20240050907Abstract: The present disclosure relates to semipermeable membranes which are suitable for blood purification, e.g. by hemodialysis, which have an increased ability to remove larger molecules while at the same time effectively retaining albumin. The membranes are characterized by a molecular retention onset (MWRO) of between 9.0 kD and 14.5 kD and a molecular weight cut-off (MWCO) of between 55 kD and 130 kD as determined by dextran sieving curves and can be prepared by industrially feasible processes excluding a treatment with salt before drying. The invention therefore also relates to a process for the production of the membranes and to their use in medical applications.Type: ApplicationFiled: May 4, 2023Publication date: February 15, 2024Inventors: Adriana BOSCHETTI-DE-FIERRO, Manuel VOIGT, Bernd KRAUSE, Markus HORNUNG, Markus STORR, Heinrich BEHR, Werner BECK, Carina ZWEIGART, Reinhold BUCK, Philipp HERBST, Joachim LOERCHER, Arnd WOCHNER

Patent number: 11596902Abstract: The invention relates to a membrane which can be used for cultivating adherent or suspension cells, in particular adherent cells, wherein said membrane allows for the adhesion and proliferation of the cells due to the irradiation of the wet or dry membrane with gamma- or beta-rays or an electron beam in a dose of from 12.5 to 175 kGy in the presence of oxygen. The resulting membrane may be used without any pre-treatment with surface-modifying substances. The invention further relates to a method for preparing said irradiated membrane which can be used for the cultivation of cells, in particular adherent cells, and to methods of using such a membrane for the cultivation of cells, in particular adherent cells.Type: GrantFiled: March 2, 2021Date of Patent: March 7, 2023Assignee: GAMBRO LUNDIA ABInventors: Bernd Krause, Markus Neubauer, Joachim Loercher
