The present invention relates to a method for amplifying a template nucleic acid, wherein the method comprises amplifying said template nucleic acid using the helicase dependent amplification (HDA) reaction in the presence of a nicking endonuclease, and wherein said template nucleic acid comprises a sequence recognized by said nicking endonuclease or a sequence recognized by said nicking endonuclease is introduced into the template nucleic acid during the HDA reaction. The invention further pertains to a kit for amplifying a nucleic acid, comprising a nicking endonuclease, a helicase and a DNA polymerase.

The invention relates to a method and a device for the automatic processing of biological samples which can have a relatively large volume and which can be further processed by a microfluidic system. A container is provided with a filter and can be or is closed. A biological sample is introduced into the container. An inlet or outlet for liquids is mounted downstream of the filter. In order to carry out processing, liquids that are present in the container are not only sucked off through the filter and passed on via the inlet or outlet, but liquids required for processing are also pumped into the container through the filter. The container can be connected to a microfluidic system in a relatively easy manner since only one conduit is required for an automated processing.
