| Extracted molecule |
genomic DNA |
| Extraction protocol |
DNA isolation for arrayCGH was performed as described elsewhere. (20) In short, formalin-fixed paraffin-embedded FFPE tissue of uterine corpus cancer was used. Cases were discarded if the tumor cell percentage was below 70%. Genomic DNA was isolated from 10*10µm thick paraffin slides. Slides were deparaffinized twice in xylene for 5 minutes, rehydrated in 100% (twice), 90%,70% ethanol and stained with hematoxylin. To remove formalin induced cross-links an overnight incubation in 1M NaSCN at 37°C was performed. Slides were subsequently washed in PBS twice for 10 minutes and air-dried. Tumor cells were collected by macro dissection by scraping from the slides and cells were transferred to a tube containing 200 µl ATL buffer (QIAamp® DNA Mini Kit cat 51304, Qiagen), 27 µl Proteinase-K was added and samples were incubated at 55°C while shaken at 450 rmp for at least 40 hours. At intervals of 4, 16 and 24 hours additional 27 µl of Proteinase-K was added (Qiagen kit). Further isolation was done following the manufacturers instructions (Qiagen).
