Abstract
The invention relates to a process for purifying and concentrating charge-bearing first molecules 9, such as proteins, nucleic acids and the like, comprising the following steps:a) preparation of a solution containing the first molecules 9, b) contacting the solution with an electrode 2 which is directly provided with a coating of second molecules 4 having affinity for the first molecules 9, andc) connecting the electrode 2 to a means 11 for generating an electric field to bring about a movement of the first molecules 9 in the solution directed relative to the electrode 2.
