| Title |
polypoid adenoma 74 |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Colorectal tissue, macrodissected [test]
|
| Organism |
Homo sapiens |
| Characteristics |
gender: F
paris classification: Ip
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Laser capture microdissection was performed on haematoxylin stained tissue section to obtain the dysplastic cells. Tissues were incubated overnight 37°C in 1M NaSCN. Subsequently, samples were treated with proteinase K for 5 days. DNA was extracted using the DNA Qiagen micro kit (Qiagen).

| Channel 2 |
| Source name |
FFPE colon DNA pool from healthy individuals [reference]
|
| Organism |
Homo sapiens |
| Characteristics |

| Data processing |
Median Signal intensity minus median Background intensity; excluding negative values. To overcome potential wave bias due to differences in GC-content of the different chromosomal regions, a smoothing algorithm was applied on our dataset as described by van de Wiel et al, Bioinformatics 2009; 25(9):1099-1104.
