<p>There is provided a method of extracting a nucleic acid analyte from a cell or virus in a sample chamber, comprising a) adding disruption beads comprising external silica or glass to the sample chamber; b) agitating the disruption beads within the sample chamber to disrupt the cell; c) adding binding particles comprising external silica or glass to the sample chamber in the presence of a chaotropic agent; d) contacting the contents of the sample chamber with a removal device with which the binding particles reversibly associate; and e) separating the removal device and associated binding particles from the sample chamber, thereby removing the nucleic acid analyte from the sample. There are also provided apparatus and kits for use with the method.</p> |
