Patent number: 11921108Abstract: A method for determining an amount of functional albumin includes providing a test sample containing a defined amount of albumin of unknown binding capacity and a reference sample containing the same defined amount of albumin having a reference binding capacity, incubating the test and reference samples with a defined amount of at least one albumin-binding marker M under conditions that allow formation of complexes of the at least one albumin-binding marker M and albumin (M:A), removing the complexes, detecting a presence or an amount of unbound marker M in the samples after removal of the complex (M:A) through a first and a second test strips that allow for a determination of an amount of unbound marker M, and determining the amount of functional albumin based on the presence or the amount detected of marker M.Type: GrantFiled: February 8, 2022Date of Patent: March 5, 2024Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Sebastian Klammt, Steffen Mitzner, Jan Stange, Emil Reisinger

Patent number: 11280780Abstract: Determining the relative binding capacity of albumin (A), and amount of functional albumin, involves at least two measurement solutions of a test and reference sample. The measurement solutions contain an albumin-binding marker M. The marker in the measurement solution of the test and reference samples exceeds the presumed available albumin binding capacity. The test sample contains a defined amount of albumin of unknown binding capacity. The reference sample contains the same defined amount of albumin having a reference binding capacity. The measurement solutions are incubated under conditions that allow M:A complexes to form. The M:A complexes are removed. The presence or amount of unbound marker M in the solutions is detected after M:A complex removal by a test strip that allows determination of the unbound marker. The relative binding capacity of albumin in the test sample based on the presence or detected amounts of unbound marker is determined.Type: GrantFiled: April 20, 2018Date of Patent: March 22, 2022Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Sebastian Klammt, Steffen Mitzner, Jan Stange, Emil Reisinger

Patent number: 6509147Abstract: A process and set-up of therapeutic immunomodulation is provided for medicine. Many illnesses (i.e. Sepsis) are, among other things, characterized by a disruption of the immune system. In spite of previous therapies using antibiotics, the mortality rate is still very high. The administration of individual cytokins has not yet resulted in any convincing results. The use of cells in an extra-corporal circulation that can adsorb or self-release immunomodulatory effect substances is a completely new type of complex therapeutic approach to such illnesses, which leads to an improvement in the health of the affected patients.Type: GrantFiled: July 14, 1999Date of Patent: January 21, 2003Assignee: Teraklin AktiengessellschaftInventors: Jens Altrichter, Jens Freytag, Steffen Mitzner, Jan Stange

Patent number: 5744042Abstract: The present invention provides a process of separating substances bound to a first protein in a first liquid by means of a membrane separating the first liquid from a second liquid, the process comprising the steps of: a) impregnating the membrane by passing along the membrane a solution comprising a first acceptor protein having an acceptor function for the substances to be separated; b) dialyzing the first liquid against the second liquid, the second liquid comprising a second acceptor protein having an acceptor function for the substances to be separated, wherein the membrane separating the first and second liquids contains tunnel-like structures that permit passage of the substances to be separated to the second liquid but exclude passage of the first protein and the second acceptor protein.Type: GrantFiled: December 12, 1995Date of Patent: April 28, 1998Inventors: Jan Stange, Steffen Mitzner, Wolfgang Ramlow
