Sample GSM182124 Query DataSets for GSM182124
Status Public on Apr 17, 2007
Title E2F4 S phase Replicate 1
Sample type genomic
 
Source name E2F4 ChIP from S-phase T98G cells
Organism Homo sapiens
Characteristics human glioblastoma cell line T98G CRL-1690
Treatment protocol Cells were incubated in serum-free medium for 3 days to induce G0 arrest, then serum was added for 24 h to induce S-phase.
Growth protocol Human T98G cells grown till 70% confluency in DMEM supplemeted with 10 % fetal calf serum
Extracted molecule genomic DNA
Extraction protocol Chromatin was prepared from formalin-fixated cells exactly as described in Rayman, Takahashi et al. (2002) Genes Dev 16, 933-947
Label biotin
Label protocol The chromatin immunprecipitated DNA (ChIP) or 2 ng of whole genomic DNA (Input) were amplified by ligation-mediated PCR, digested with Dnase I to give fragments of ~50 bp.
The DNA fragments were end-labelled with biotin in a TdT-catalyzed reaction.
 
Hybridization protocol Affymetrix fluidics protocol EukGE-WS2v4_450
Scan protocol Scanning was carried out on an Affymetrix scanner GCS3000. The scan protocol was contained in a .cif file for chip type Hs_PromPR_v02.
Description Chromatin from S-phase synchronized T98G cells immunoprecipitated with anti-E2F4 antibody, replicate 1 out of 3
Data processing Affymetrix GCOS processed image files to generate .CEL files.
MAT (Model-based Analysis for Tiling Arrays) analysis algorithm used to detect regions enriched by chromatin immunoprecipitation (ChIP) on Affymetrix Human Promoter Array 1.0R (ChIP-chip).
