Apparatus for separating a target reagent attached to a solid phase magnetic support from a mixture of reagents comprises a support means (1, 13) for supporting an array of reaction vessels (16), and an associated array of permanent magnets (4, 21) arranged such that, when an array of reaction vessels is supported in the support means and the apparatus is in use for separating a target reagent from a mixture of reagents in one or more of the reaction vessels, each magnet is positioned so as to be able to exert a magnetic force on an associated reaction vessel or vessels in the array of reaction vessels, which magnetic force serves to hold the magnetic support and attached target reagent in a fixed position relative to the magnet, thus allowing the remaining mixture of reagents to be removed from the reaction vessel. The apparatus is of particular use in the preparation of DNA products for use in DNA sequencing reactions. |
