Claim 20:
21. A method for determining integrity of non-naturally occurring oligonucleotide sequences encoded with ternary or quaternary base system DNA data stored on a storage medium comprising a solid support matrix, wherein the matrix is fibrous, wherein said matrix includes a reagent mix in a dry form, wherein the reagent mix comprises a combination of a weak base, a chelating agent, a stabilising reagent comprising a chaotropic salt, and an anionic surfactant, and wherein the storage medium includes a visual delineation around an area for holding the DNA data comprising: (i) a printed boundary on the fibrous matrix configured to show where the DNA data is stored or (ii) an indicating dye such as chlorophenol red or phenol red, which is configured to discolor, thereby showing where the DNA data is stored on the storage medium, said method including the steps of:
sampling medium from the visual delineated area; and
performing an STR (short tandem repeat) profile analysis on a portion of the DNA data stored on the medium sampled from the visual delineated area.
