Channel 2
Source name female reference DNA
Organism Homo sapiens
Characteristics tissue: Pooled DNA from the blood of 18 normal female individuals
Extracted molecule genomic DNA
Extraction protocol DNA isolation protocol available via www.vumc.nl/microarrays. Also described in Buffart et al, J Pathol. 2007 Jan;211(1):45-51
Label Cy5
Label protocol Labeling was done by random priming (Bioprime DNA Labeling System, Invitrogen, Breda, The Netherlands)
 
 
Hybridization protocol As described in Buffart et al, J Pathol. 2007 Jan;211(1):45-51
Scan protocol Slides were scanned using the Agilent microarray scanner, protocol according to Agilent.
Description A pool of DNA from blood of normal individuals
Data processing Bluefuse software version 3.4 (BlueGnome, Cambridge, UK) was used for automatic feature extraction. Spots were excluded when the quality flag was below 1 or the confidence value was below 0.1. Log2 tumor to normal ratio was calculated for each clone and median block normalization was used to normalize the data.
