A total of 12 unselected DNA preparations from FFPE breast tumours with corresponding multiplex PCR quality controls. (A) DNA was isolated from archival blocks stored between 6 (lane b) and 29 (lane l) years. Lane M indicates the molecular size standard (bp). Sample a through l were fixed and stored 11, 6, 22, 20, 18, 11, 8, 7, 19, 17, 16 and 29 years ago, respectively. Lanes in bold a, b, d, f, h, j and k indicate samples with successful aCGH. The oldest samples in this panel successful in aCGH are in lanes d, k and j (20, 17 and 16 years). (B) Agarose gel showing multiplex PCR product sizes in bp (see Materials and Methods) for the corresponding samples above.
