A magnetic separation method which comprises the steps of a bringing a vessel having a bottom end and containing a liquid suspension of magnetically attractable particles into proximity with a magnet system whereby there is formed an annular or part-annular pellet comprising the magnetically attractable particles close to, but not at, the bottom end of the vessel
In another aspect, the invention provides apparatus for performing the magnetic separation method which apparatus comprises an array of vessels each to contain a liquid suspension of magnetically attractable particles a pipetting system for transferring liquid to and from the array of vessels and a magnet system mounted for movement relative to the array of vessels, so as to be either free of the
The invention provides magnetic systems for this purpose, shaped to form an annular or part-annular pellet close to the bottom of the vessel. The systems are suitable for automation.

Nov 14, 1996 The precipitated bacterial chromosomal DNA then aggregates. A nucleic acid precipitation reagent e.g. isopropanol, ethanol or polyethylene glycol in aqueous sodium chloride containing magnetic beads e.g. FMP particles, Amersham International plc. is then added to the salt-treated lysate of the plasmid-containing bacterial host cells.
Us6129848a - method for continuous magnetic separation of.A magnetic system and apparatus having a multi-dimensional gradient for continuous, on-line separation of components from a mixture of chemical entities which comprises at least one separation chamber with a plurality of channels and a plurality of magnets, and a method is provided for continuously and magnetically separating and.
A method of recovering a first material, e.g. plasmid DNA from a solution containing pre-precipitated second material, e.g. genomic DNA and cellular debris, by precipitating the first material in the presence of magnetically attractable beads which become non-specifically associated with the newly formed precipitate, using a magnet to draw down the beads and the newly formed precipitate, and ...

Oct 25, 2006 Nucleic acid separation using magnetic beads is described in Alderton et al. 1992 and in WO1991012079 as well as in US 5,523,231 Amersham. These magnetic beads are able to absorb the nucleic acid after a salt-ethanol precipitation. The approaches are not nucleic-acid-specific, i.e. the magnetic beads adsorb other bio-substances in parallel.
Feb 01, 1992 Starting with a phage supernatant, the entire procedure is carried out in the same reaction vessel and all separation steps are based on a novel application of magnetic bead separation. The design of a 96-well magnetic separator is presented and the application of the method for large-scale sequencing is discussed.
