abstract |
The present invention involves new processes and equipment for the isolation and purification of nucleic acids on surfaces. The invention is aimed at processes which use surfaces, e.g. porous membranes, at which, out of the sample containing the nucleic acids, in a simple manner, nucleic acids can be immobilized and can be released by means of equally simple process steps, whereby the simple carrying out, according to the invention, particularly permits the performance of the processes fully automatically. A further aspect of the invention is aimed at the fact, that nucleic acids are bonded to an immobile phase, particularly a membrane, in such a way, that they can be released again from this phase without any complications in a following reaction step and, if applicable, can be used for further applications, e.g. restrictive digestion, RT, PCR or RT-PCR or in any other of the above mentioned analytical- or enzyme reactions. Finally, the invention is directed at a special isolation container with which the processes can be executed according to the invention. |
