Sample GSM562725 Query DataSets for GSM562725
Status Public on Jul 07, 2010
Title AB8898_H3K9ME3339901_N2_EEMB_1 extraction1_array1
Sample type genomic
 
Channel 1
Source name AB8898_H3K9ME3339901_N2_EEMB_1 extraction1_array1 channel_1
Organism Caenorhabditis elegans
Characteristics strain: N2
developmental stage: Early Embryo
genotype: wild type
sex: mixed Male and Hermaphrodite population
Growth protocol Worm_embryo_growth_and_harvest_vSS3. Embryos were prepared by bleaching from gravid N2 adults grown in standard S-basal media liquid culture. Live embryos were cross-linked in M9 + 1.85 % formaldehyde for 30 minutes at room temperature. Embryos were then washed twice with M9 Buffer, once with 100 mM Tris-HCl pH 7.5 and once with 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. For a detailed protocol see http://www.modencode.org/.
Extracted molecule genomic DNA
Extraction protocol Worm_embryo_extraction_vSS2. Embryos were resuspended in FA buffer (50 mM HEPES/KOH pH 7.5, 1mM EDTA, 1% Triton X-100, 0.1% sodium deoxycholate; 150 mM NaCl) + protease inhibitors. Sample was dounced 30 times using tight pestle at 4ºC, then sonicated 9 times on ice at the following settings: 30 sec; power output 3; 70% duty cycle. Cell debris was removed by centrifuging at 13,000 rpm for 15 minutes at 4ºC and taking the supernatant. Supernatants were filtered through Millipore Ultrafree-MC 0.45 ?m filter units (cat. UFC30HV0S) at 13,000 rpm, 4°C for 1 minute to remove lipids. Protein concentration was determined, and extracts were aliquoted and stored at -80ºC. For a detailed protocol see http://www.modencode.org/.
Worm_chromatin_immunoprecipitation_vPK1. Appropriate amount of extract is incubated overnight with a proper amount of antibody (exceptional antibodies due to better results are incubated 2hrs). Afterwards, 40ul of equilibrated magnetic beads (either protein A or G, depending on antibody) are added and incubated for 2 hrs. Later, washes with FA, 500mM-salt FA, 1M salt FA, TEL, and TE buffer are performed and DNA is eluted in elution buffer (1% SDS in TE with 250 mM NaCl) ? two times with 57 ?l volume each, at 65°C. Samples are treated with RNAse, proteinase K and then crosslinks are reversed overnight at 65°C. DNA is purified on qiagen PCR purification columns, tested by q-PCR for ChIP quality, and stored in -20°C for future applications.
Worm_LM-PCR_Amplification_for_ChIP-chip_vSS2. ChIP DNA was amplified with a modified ligation mediated PCR (LM-PCR) protocol derived from FlyChip protocol version 1.2 from R. Auburn: http://www.flychip.org.uk/protocols/chip/lm_pcr.php. For a detailed protocol see http://www.modencode.org/.
Label Cy5 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.

Data processing ChIP-chip normalization standard nimblegen:JL:1 protocol. ChIP-chip_normalization_standard_nimblegen_v1. The log2-ratio ratio of intensity from sample/reference channel was scaled to center the ratio data around zero by subtracting the bi-weight mean for the log2-ratio values for all features on the array from each log2-ratio value. This was performed using NimbleScan software according to the NimbleScan v2.4 User?s Guide and chapter 6 of the NimbleGen Arrays User?s Guide ChIP-chip Analysis (version 3.1, 27 May 2008) at Roche NimbleGen. Processed data are obtained using following parameters: genome version is WS180
