| Extraction protocol |
DNA isolation WI protocol; For all tissues Protocol adapted from Qiagen DNeasy Blood and Tissue Handbook (July 2006). Using the DNeasy Blood and Tissue Kit: 1. Spin down samples and resuspend in 180uL ATL buffer. 2. Add 20uL proteinase K. Incubate at 56C until tissues are lysed (typically overnight for salivary gland tissues, four hours for other cell types). Vortex occasionally. 3. Vortex for 15s. Add 200uL buffer AL. Vortex again, and then add 200uL 100% EtOH. Vortex again to mix. 4. Pipet mixture into supplied DNeasy Mini Spin column placed in provided 2mL collective tube. Centrifuge for 1min at >6000g (14000rpm in a tabletop centrifuge is fine). 5. Place column in a fresh collection tube. Add 500uL buffer AW1, centrifuge for 1min at >6000g. Discard collection tube. 6. Transfer spin column to a fresh microcentrifuge tube. Pipet 50uL buffer AE onto column membrane. Incubate at room temperature for 1min, and elute by centrifuging for 1min at >6,000g.

| Label protocol |
Labeling WI protocol; For All Tissue Types Protocol Adapted from Agilent Technologies’ “Oligonucleotide Array-Based CGH for Genomic DNA Analysis” Protocol Handbook (Version 2.0, August 2005). The BioPrime Array CGH Genomic Labeling System (18095-011, Invitrogen) was used to prepare samples for CGH arrays. Cye-dyes were purchased from Amersham (25nmol, PA53022/PA55022). Label 3ug of genomic DNA (recovered from 150 larval salivary glands or 16C follicle cell nuclei from 300 pairs of ovaries). 50uL of embryos yields about 7-9ug of DNA. 1. Add 20uL of the 2.5x Random Primers solution to your previously prepared salivary gland gDNA. Transfer tube to a heat block at 95C and incubate for 5 minutes. Afterwards, immediately incubate sample on ice for an additional 5 minutes. 2. Prepare the labeling reaction mix on ice in the order indicated. 10x dUTP mix 5uL Cy3 or Cy5 –dUTP 3uL Exo-Klenow 1uL Mix this labeling reaction mix with your salivary gland gDNA (incubating on ice). 3. Transfer sample to a water bath at 37C for 2 hours. 4. Remove sample from water bath and add 5uL of Stop Buffer. 5. Concentrate labeled DNA with a microcon YM-30 filter according to manufacturer’s instructions for a final volume of 150uL, for each tube. 6. Quantitate total amount of incorporated dye in each sample using a Nanodrop. Combine up to 200 picomoles of labeled sample into a single tube, for a maximum volume of 150uL. Save the rest for technical replicates.

| Scan protocol |
This scanning protocol outputs raw images of intensity values resulting from the hybridization of the DNA sample to the microarray slide. The raw tiffs are quantified and output in an Agilent text format. We then mangle the Agilent data into a pseudo nimblegen format.
|
| Data processing |
Normalization_and_peak_calling:DM:1 protocol. Normalization and peak calling protocol; Agilent data files are converted to a nimblegen like format for processing by MA2C. pMA2C -- pyhton MA2C (http://liulab.dfci.harvard.edu/MA2C/MA2C.htm) Parameters are passed as a tag file which we generate in Array Scanning protocol. Processed data are obtained using following parameters: tag file is http://macalpine-lab.duhs.duke.edu/files/modencode/Fatbody_CGH/1M_Array/fatbody_1M.tag
