products to the filter membrane of a 96 gauge corrugated plate in less than 10 minutes previous procedures based on the binding of nucleic acids to a solid phase require about 45 minutes to 1 hour in addition the process sequence is also extremely simple and only consists of mixing the pcr starting solution with a binding buffer according to the invention the transfer of the solution to the filter plate the suctioning through of the solution and the subsequent elution of the pcr products using water or a 10 mm tris buffered aqueous solution thus pcr products can be purified in an extremely timesaving harmless and cost effective manner the throughput can therefore be increased dramatically also for less sophisticated equipment e g a robot no longer requires a washing tool the quality of the purified pcr products is very high which one can see in the clean sequence reactions example 2 furthermore surprisingly one can see that nucleic acids having excellent quality and quantity can also be isolated from complex biological samples without washing steps or using an alcohol less washing buffer the isolation of a dna plasmid described in an example in unexamined patent de 100 33.
