An automatic separator of macromolecules or fragments thereof comprises: at least one element for the migration and transfer (3) of said macromolecules comprising at least one electrophoresis gel (31) associated with a membrane (32) for transfer and attachment of said macromolecules; means (21) for supplying said macromolecules to the migration and transfer element(s); a migration tank (40) comprising a removable internal structure consisting of a plurality of frames (42) for accommodating the migration and transfert element(s); at least one means for applying an electric field to induce the electrophoretic migration of the macromolecules; at least one means for transferring the macromolocules between the various parts of said migration and transfer element and attaching them to said transfer and attachment menbrane; and a microprocessor for automatic sequential control of said migration and transfer element(s), of said means for supplying the macromolecules, of said means for applying an electric field and of said transfer means. For separation of nucleic acids, it also includes a treatment station (20)for digestion of said nucleic acids, located upstream of the migration and transfer elements. |
