  • Process and device for the electrophoretic separation, purification and concentration of charged or polarizable macromolecules
    Patent number: 4948481
    Abstract: In the process for the electrophoretic separation, purification and concentration of charged or polarizable macromolecules from a mixture of these molecules in a separation column with a slab or bar gel as the support, the macromolecules separated in the support are caused to migrate out of the support by means of the electrophoretic current and are fed into a multielectrode collector (13) via a molecule detector (5) and a distributor (6). Each of the electrodes of the multielectrode collector is individually activated according to a signal coming from the molecule detector (5).
