A separation device is disclosed comprising an array of magnetic or magnetisable members (2) and a corresponding array of protective sleeves (6) therefor associated with the magnetic members (2). The magnetic members (2) are removable from the sleeves (6). The sleeves (6) in turn may be removably introduced into the wells (5) of a micro-titre plate (4). Also disclosed is a method of preparing single-stranded DNA (ssDNA) from double-stranded DNA (dsDNA) comprising the steps of immobilising a strand of the dsDNA on a solid magnetic or magnetisable carrier, inserting a magnetic or magnetisable member into a solution containing the DNA to attract said carrier, separating the dsDNA into single strands, and thereafter removing the member from the solution thereby removing ssDNA from the solution. |
