  4. 3. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Författare :Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Sammanfattning : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. LÄS MER
