  1. 1. Simulation of periodic counter-current chromatography purification of monoclonal antibodies with column degradation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Friberg; [2022]
    Nyckelord :Counter-current chromatography; PCC; Monoclonal antibodies; Affinity chromatography; Process control; Chemical engineering; Process simulation; Chemistry;

    Sammanfattning : The purification process of monoclonal antibodies (mAbs) for therapeutic drugs is expensive, especially the chromatography step in which the mAbs are separated from other proteins and cells present in the feed. The antibodies are separated from the feed using affinity chromatography, where only the antibodies interact with active sites within the column, whereas the rest passes through the column without stopping.

  2. 2. Development of a Graphical User Interface For Easier Overview of Historical Chromatography Data

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Agnes Hermansson; [2021]
    Nyckelord :GUI; graphical user interface; PyQt5; Orbit; Chromatography; data visualization; chemical engineering; Chemistry;

    Sammanfattning : Chromatography is a separation technique frequently used in the purication of medicinal drugs. In studies and project at the department of chemical engineering at Lund University a large amount of data have been generated through the use of their research software Orbit and their ÄKTA chromatography system.

  3. 3. Towards autonomous antibody purification

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Frida Heskebeck; [2019]
    Nyckelord :Chemical engineering; Kemiteknik; Simulation; Chromatography; Periodic counter-current chromatography; Python; PCC; Technology and Engineering;

    Sammanfattning : The vision of antibody purification is to have the whole process fully automatic. It is often desirable to have a continuous process since that reduces the costs for production and the size of the used equipment. It is necessary to supply buffer solutions to the purification steps, and as part of the vision; this should be done automatically. LÄS MER

  4. 4. A Model-based Approach to Evaluating Chromatography Capture Steps

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jakob Ulmestig; [2017]
    Nyckelord :Periodic counter-current chromatography; PCC; Continuous chromatography; Continuous bioprocessing; Sequential capture; Model based optimization; Breakthrough curve; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Recent advances in upstream production of biopharmaceuticals have not yet been matched by equivalent advances in the downstream processing. As chromatography is currently the primary downstream processing method in production of biopharmaceuticals new methods for multicolumn processes are being developed. LÄS MER
