Abstract:
1. A method for isolating a target nucleic acid, from a sample comprising said target nucleic acid, said method comprising (a) contacting said sample with a nucleic acid binding matrix, (b) binding at least part of said target nucleic acid to said nucleic acid binding matrix, wherein said nucleic acid binding matrix is treated simultaneously or has been previously treated with at least one compound comprising a metal substance selected from the group consisting of metals of groups 13 to 16, semimetals and transition metals, wherein said compound is optionally in dissociated form, solvated form and/or in a form of a salt, wherein said metal substance is employed in order to reduce non-target nucleic acid contaminations in an obtained target nucleic acid preparation; and (c) obtaining said target nucleic acid from said nucleic acid binding matrix, wherein the nucleic acid binding matrix comprises a silica surface and at least part of the nucleic acid binds to the silica surface.
