Sample GSM1315602 Query DataSets for GSM1315602
Status Public on Sep 29, 2014
Title CBP_null1_DP
Sample type SRA
Source name primary CBP null MEF (e14.5)
Organism Mus musculus
Characteristics strain: C57BL/6 x 129Sv (F1)
treatment: 2hrs 100uM dipyridyl
passage: 5
chip antibody: CBP (CREBBP) Brindle 8690
Treatment protocol 25ul of 100mM 2',2'-dipyridyl or ethanol vehicle was added to each plate and plates were returned to normoxia 5% CO2 incubator for 2hrs. Medium was then removed from the plates and 15ml 3% paraformaldehyde in PBS was added and cells were allowed to fix for 20min at room temperature. Fixed adherent cells were washed 2x with PBS and scraped from plates into PBS to harvest. Cells were lysed in buffer containing 1% SDS.
Growth protocol 6 15 cm dishes of each p5 wild type and CBP conditional (flox//flox) MEF were plated at 4x10^6 cells/dish in 25ml DMEM+10%FBS containing Cre recombinase expressing adenovirus at an MOI of 100 and grown in a 3% O2 5%CO2 incubator. Medium was changed 16hrs later for 25ml DMEM + 10%FBS and MEFs were grown for 48hrs in 3% O2 5%CO2 incubator. MEFs were transferred to a normoxia 5% CO2 incubator and grown for 24hrs.
Extracted molecule genomic DNA
Extraction protocol Cell lysates were sonicated (5x 10sec @ 15micron amplitude, MSE Soniprep 150) and immunoprecipitated using CBP antibody (MEFs lacking CBP provide control for antibody specificity)
library prepared according to Illumina protocol "Preparing Samples for ChIP Sequencing of DNA" (2007). Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were band isolated from an agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation.
