Sample GSM622057 Query DataSets for GSM622057
Status Public on Aug 21, 2011
Title UL3 Bare, repeat 1
Sample type genomic
 
Source name Mononucleosomal MNase fragments from UL3 cells, bare DNA
Organism Homo sapiens
Characteristics cell line: UL3 (U20S w/ GR and MMTV-luc)
Treatment protocol no treatment (control)
Extracted molecule genomic DNA
Extraction protocol Chromatin was extracted from cells using NP40 lysis, digested with micrococcal nuclease (MNase) to ~70% mononucleosomes and mononucleosomes isolated by PAGE and elution
Label Cy3
Label protocol 1 to 4 micrograms of each mononcleosomal sample were labeled with Cy3 or Cy5 by Nimblegen services, according to their standard procedures
 
Hybridization protocol Hybridization was performed by Nimblegen accoring to standard procedures
Scan protocol Scanning was performed by Nimblegen using Nimblescan version 2.4.27
Description MNase digested bare DNA from UL3 cells (sample 1)
Data processing For each position, two forward and two reverse oliogs were tiled on the array. Data for each set of oligos (nucleosomal & bare) were normalized to 1.0, and the ratio of nucl/(average bare 1 & bare2) determined. The median nucl/bare values for all 4 oligos were then quantile normalized for comparisons between conditions. The data was then locally smoothed by a combination of exponential smoothing of oligos within +/-40 bp (*0.5^(BP/10)) and by down-weighting positions where the deviation from the median value for F1,F2,R1 & R2 oligos was greater than average (*0.5^(deviation/avg_deviation)). Data processing was performed using custom PERL programs.
