Sample GSM4195043 Query DataSets for GSM4195043
Status Public on Dec 01, 2019
Title DamID AML12_shCtrl_rep1
Sample type genomic
 
Channel 1
Source name AML12
Organism Mus musculus
Characteristics cell line: AML12 cells
lenti-virus expression: Dam-LAMINB1
Treatment protocol The shRNA lentiviruses were prepared as previously described (Fu et al., 2015). Then AML12 cells were infected with 200 μl of virus concentrate in a well of six-well-plates. Medium was changed 24 hours after transfection, and then collect cells 5 days after transfection.
Growth protocol AML12 cells were cultured in DMEM/F12 supplemented with 10% fetal bovine serum, ITS Liquid Media Supplement, and 0.1μM dexamethasone at 37 °C and 5% CO2.
Extracted molecule genomic DNA
Extraction protocol 2×106 AML12 cells were planted in 6-well plates, and infected with lenti-virus expressing Dam or Dam-Lamin B1 after 48 hours. gDNA was isolated with the Dneasy Tissue kit (Qiagen) per the manufacturers protocol after 72 hours. 2.5 μg of gDNA was digested with DpnI (New England Biolabs), adapters were ligated with T4 ligase (New England Biolabs), and the ligation reaction was subsequently digested with DpnII (New England Biolabs). 500 ng of the DpnII digested material was used as input for a PCR amplification of methylated fragments (MePCR),see Vogel et al., 2008, Nature Protocols for details.
Label Cy5
Label protocol Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.
 
Channel 2
Source name AML12
Organism Mus musculus
Characteristics cell line: AML12 cells
lenti-virus expression: Dam-only

Label Cy3
Label protocol Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.
 
 
Hybridization protocol Hybridized to Agilent-027414 arrays.
Scan protocol Scanned on an Agilent Technologies Scanner G2505C.
Description Replicate 1 of 2 shCtrl AML12 cells
Data processing Agilent Feature Extraction Software was used for background subtraction and LOWESS normalization. we also smoothed the probe signals using a moving average approach with a window size of 40k bps. The smoothing procedure takes into consideration of the spatial correlation of signals.
