Devices and methods for removing pathogens from biological fluids

Method for removing pathogens from biological liquids, said biological liquids containing at least one pharmaceutically active molecule, said method comprising the steps of

• providing a biological liquid, wherein pathogens are potentially present, in an apparatus comprising an anode and a cathode and a membrane suitable for separating said pathogens from said pharmaceutically active molecule, said separation means being positioned between said anode and said cathode,
• applying current between said anode and said cathode, thereby causing one of said pathogens or said pharmaceutically active molecule to pass said separation means and
• recovering said pharmaceutically active molecule in a form being essentially free of said pathogens and
• wherein said biological liquid is subjected to at least one virus inactivation step in said apparatus.
