Sample GSM562600 Query DataSets for GSM562600
Status Public on Jul 07, 2010
Title JL00002_SDC3_N2_MXEMB_1_A extraction1_array1
Sample type genomic
 
Channel 1
Source name JL00002_SDC3_N2_MXEMB_1_A extraction1_array1 channel_1
Organism Caenorhabditis elegans
Characteristics strain: N2
developmental stage: Mixed Embryo
genotype: wild type
sex: mixed Male and Hermaphrodite population
Growth protocol Worm_embryo_growth_and_harvest_v1. Embryos were prepared by bleaching from gravid N2 adults grown in standard S-basal media liquid culture. Live embryos were cross-linked in M9 + 2% formaldehyde for 30 minutes at room temperature followed by quenching with 125mM glycine for 5 minutes. Embryos were then washed twice with M9 Buffer and once by FA buffer (50 mM HEPES/KOH pH 7.5, 1 mM EDTA, 1% Triton X-100, 0.1 % sodium deoxycholate; 150 mM NaCl). Pellets were frozen at -80C.
Extracted molecule genomic DNA
Extraction protocol Worm_embryo_extraction_v1. Embryos were resuspended in FA buffer (50 mM HEPES/KOH pH 7.5, 1 mM EDTA, 1% Triton X-100, 0.1 % sodium deoxycholate; 150 mM NaCl) + protease inhibitors (Calbiochem Cat# 539131). Using a Branson sonifier microtip, samples were sonicated on ice at the following settings: 35% amplitude, 0.9 sec on, 0.1 sec off, 12 pulses, 7 times. Cell debris was removed by centrifuging at 13,000 g for 15 minutes at 4ºC and taking the supernatant. Protein concentration was determined by Bradford Assay and extracts were aliquoted at stored at -80C.
Worm_chromatin_immunoprecipitation_v1. 2mg extract was used for each ChIP with 10% taken as input directly into elution buffer (1% SDS in TE, 250 mM NaCl) and treated with RNAse. Antibody was added to each IP sample and incubated overnight at 4C. Immune complexes were incubated (2hrs at 4C) with 50 uL IgG dynabeads (Dyna), captured using a magnetic holder, and washed 5 minutes with 1.5mL of each of the following solutions: ChIP Buffer, ChIP Buffer+1M NaCl, ChIP Buffer+500mM NaCl, TEL Buffer (10mM Tris-HCl pH 8.0, 250mM LiCl, 1% NP-40, 1% sodium deoxycholate, 1mM EDTA), and 2X TE (10mM Tris-HCl pH 8.0, 1mM EDTA). Samples were eluted twice with 150uL elution buffer for 15minutes at 65C. Samples were treated with proteinase K at 55C for 1-2hrs then transfer to 65C overnight to reverse crosslinks. DNA was cleaned up Qiagen PCR purification kit and concentrated using by Speed vac.
Worm_Whole_Genome_Amplification_for_ChIP-chip_v2. Samples were amplified using a modified Whole Genome Amplification Kit protocol (Sigma).
Label Cy3 dye
Label protocol ChIP-chip_label_hyb_nimblegen_v1. DNA was labeled and hybridized to C. elegans tiling array by Roche NimbleGen according to the protocol described in chapter 3 and 4 of the NimbleGen Arrays User?s Guide ChIP-chip Analysis, Version 3.1, 27 May 2008. Briefly, Amplified IP or input DNA was either labeled with Cy5 or Cy3 in the presence of Klenow fragment. The reaction was stopped by the addition of EDTA. Labeled DNA was recovered by isopropanol precipitation, and dried. The labeled DNA was hybridized to C. elegans tiling array for 16 - 20 hours at 42°C.

Scan protocol ChIP-chip_scanning_nimblegen_v1. Array scanning and raw data extraction were performed at Roche NimbleGen, according to the protocol described in chapter 5 and 6 of the NimbleGen Arrays User?s Guide ChIP-chip Analysis, Version 3.1, 27 May 2008. Briefly, array signal was scanned by using a GenePix 4000B Scanner with associated software and saved as .tif files of the 532nm and 635nm images individually. Raw signal intensities of the images were extracted and saved as .pair files by using NimbleScan software according to the NimbleScan v2.4 User?s Guide.

Data processing ChIP-chip normalization standard zscore:JL:2 protocol. ChIP-chip_normalization_standard_zscore_v2 First, the ratio of intensity from sample/reference channel was transformed to log2 space. Second, z-scores were obtained for each probe by standardizing the data by subtracting the mean and dividing by the standard deviation of all probes. Processed data are obtained using following parameters: genome version is WS180
