Abstract
There is provided a process for the separation of molecules from a suspension comprising cells at a concentration of at least 56×10cells/ml, comprising the steps of: a) providing magnetic particles having a specific interaction with said molecules to be separated, b) mixing the magnetic particles with the cell suspension containing the molecules, c) bringing the cell suspension in contact with a magnetic field provided by a magnetic separation device to collect the magnetic particles, d) decreasing or removing said magnetic field and collecting said magnetic particles carrying said molecules, and e) removing said molecules from said magnetic particles, to provide a concentrated fraction of said molecules, and/or provide partial or complete removal of impurities and cells from the fraction containing the molecules. Advantages include that the yield increases, the volume of the bioreactor and other equipment can be made smaller so that the process becomes more economical.
