Description |
Identification of in vivo CTCF binding sites in the Drosophila genome.
|
Data processing |
Spotfinding performed with Dapple (Buhler J. et al (2000). Dapple: improved techniques for finding spots on DNA microarrays. University of Washington technical report, UWTR 2000-08-05).
VSN normalisation of 4 slides in an experimental group - VALUE is the VSN normalised ratio of experimental (anti-CTCF-enriched to control). All other data are raw un-normalised values.
