Sample GSM712549 Query DataSets for GSM712549
Status Public on Dec 22, 2011
Title Drosophila-Cbx-replicate1 (Test vs Mock) [Agilent-014817]
Sample type genomic
 
Channel 1
Source name [MockIP_WCE] CbxHM/+ wing discs
Organism Drosophila melanogaster
Characteristics genotype/variation: CbxHm/+
developmental stage: Third Instar larvae
tissue: wing discs
Growth protocol Wildtype (CS) flies were crossed to flies of CbxHm/TM6B genotype and reared at 25oC. From resultant progeny CbxHm/+ wing discs were manually dissected in chilled PBS and fixed in 1% formaldehyde solution at room temperature. Chromatin was sheared to obtain average 500 bp fragments and pulled down using polyclonal antibodies generated against N-terminal region of Ubx
1:500 dilution of Ubx antibody was used to carry out pull down in 300 µl volume. Upstate Ez ChIP kit (Catalog # 17-371) was used for binding and washing the immune complex as per manufacturer's instructions.
Extracted molecule genomic DNA
Extraction protocol DNA was eluted and processed as per Agilent ChIP-on-chip protocol available at www.agilent.com
Label Cy3
Label protocol The LMPCR samples (1.5 micrograms each) were labeled in replicates using Agilent Genomic DNA Labeling Kit PLUS and Cy3 or Cy5 dUTP from Agilent. DNA yield and incorporation of label (specific activity) was measured using NanoDrop spectrophotometer. For all hybridizations, 5 micrograms each of Cy3-labeled Mock IP (labelled as WCE in raw data) was mixed with 5 micrograms of Cy5-labeled Test-IP DNA
 
Channel 2
Source name [ChIP fraction] CbxHM/+ wing discs
Organism Drosophila melanogaster
Characteristics genotype/variation: CbxHm/+
developmental stage: Third Instar larvae
tissue: wing discs
chip antibody: anti-Ubx (against N-terminal region of Ubx protein)
chip antibody supplier: generated in-house

Hybridization protocol Using Agilent’s In situ Hybridzation kit 5184-3568. As per Manufacturer's instructions.
Scan protocol Post-hybridization, the slides were washed as per Agilent protocol and scanned at 5 micron resolution
using Agilent Microarray Scanner.
Description Rep1_Agilent-014817
Biological replicate 1 of 3 slide 2, Cbx discs, Ubx ChIP
Agilent Feature Extraction File: US45103024_251481710121_S01.txt
Data processing Agilent Feature Extraction Software (v 10.2) was used for background subtraction and LOWESS normalization. The maximun distance(bp) for two probes to be considered as neighbors was taken as 500 bp in chip analytics software. The updated Agilent design file was used to extract the data Build April 2006. (dm3).
