  • Removal of biological contaminants
    Publication number: 20050224355
    Abstract: A method of removing a biological contaminant from a mixture containing a biomolecule and the biological contaminant, the method comprising: (a) placing the biomolecule and contaminant mixture in a first solvent stream, the first solvent stream being separated from a second solvent stream by an electrophoretic membrane; (b) selecting a buffer for the first solvent stream having a required pH; (c) applying an electric potential between the two solvent streams causing movement of the biomolecule through the membrane into the second solvent stream while the biological contaminant is substantially retained in the first sample stream, or if entering the membrane, being substantially prevented from entering the second solvent stream; (d) optionally, periodically stopping and reversing the electric potential to cause movement of any biological contaminants having entered the membrane to move back into the first solvent stream, wherein substantially not causing any biomolecules that have entered the second solvent st

  • Purification of blood clotting proteins
    Publication number: 20050199498
    Abstract: A method of separating a blood clotting protein from a mixture of blood clotting protein and at least one contaminant, the method comprising: (a) placing a blood clotting protein and contaminant mixture in a first solvent stream, the first solvent stream being separated from a second solvent stream by a first electrophoretic membrane; (b) selecting a buffer for the first solvent stream being a pH greater than the isoelectric point of the blood clotting protein; (c) applying an electric potential between the first and second solvent streams causing movement of at least some of the contaminants through the membrane into the second solvent stream while the blood clotting protein is substantially retained in the first solvent stream, or if entering the membrane, being substantially prevented from entering the second solvent stream; (d) optionally periodically stopping and reversing the electric potential to cause movement of any blood clotting protein having entered the membrane to move back into the first solven
