  • Processes for the production of chemically-modified heparins
    Patent number: 10023659
    Abstract: The present invention relates to a process for the production of heparin derivatives having an average molecular weight of from about 4.6 to about 6.9 kDa and an anti-factor Xa activity of less than about 10 IU/mg, comprising the steps of oxidation of unfractionated heparin, depolymerisation and reduction of resulting terminal groups.
    Type: Grant

    Date of Patent: July 17, 2018
    Assignee: Dilafor AB
    Inventors: Per-Olov Eriksson, Erik Yngve Holmer
  • Low anticoagulant heparins
    Patent number: 9480701
    Abstract: The present invention relates to a chemically modified heparin, with an antifactor II activity of less than 10 IU/mg, an antifactor Xa activity of less than 10 IU/mg and an average molecular weight (Mw) between about 6.5 and 9.5 kDa. Also disclosed is a method of preparing the heparin and its medical use, including treatment of malaria.

  • NEW PROCESS AND SYSTEM FOR MAGNETIC SEPARATION
    Publication number: 20160184737
    Abstract: A process for large scale separation of molecules comprising the steps of providing magnetic porous particles having an affinity to said molecules to be separated; mixing said magnetic porous particles with a solution containing said molecules; bringing said mixture in contact with a magnetic separation device comprising a flow channel and at least one magnetic element; removing said at least one magnetic element and collecting the magnetic porous particles carrying said molecules; separating said molecules from said magnetic porous particles; obtaining a concentrated fraction of said molecules; and recirculating the magnetic porous particles. A system for performing this process.
