Abstract
The present invention relates to the readily automated methods for the separation of biomolecules, such as proteins or nucleic acids. More specifically, the invention relates to a separation device, which includes at least one column provided with a bottom liquid inlet/outlet and adapted to receive a separation media. At least part of an elongated frit has been arranged substantially parallel to the column side walls, segregating the separation media from the bottom liquid inlet/outlet. The elongated frit may be shaped as a tube and should have a porosity that serves to retain separation media within the column during sample processing. Further, the invention relates to a method of separating at least one target molecule from a liquid, which method comprises providing at least one column provided with a bottom liquid inlet/outlet and optionally with a top liquid inlet. The column retains a separation media; and at least part of an elongated frit has been arranged substantially parallel to the column side walls to segregate the separation media from the bottom liquid inlet/outlet. A liquid sample is processed in said column in a method including aspiration and dispensing of fluid to and from the bottom liquid inlet/outlet; adding a liquid at the top liquid inlet; or any combination thereof.
