Sample GSM5452254 Query DataSets for GSM5452254
Status Public on Jul 12, 2022
Title Control H3K27ac ChIP-seq
Sample type SRA
Source name C2C12 myoblast
Organism Mus musculus
Characteristics cell type: C2C12 myoblast
strain: none
antibody: H3K27ac (ab4729, Abcam)
Treatment protocol To delete PAM-1 exon1, target-specific guide RNAs (gRNAs) were designed using CRISPR design tool (, followed by cloning into BbsI digested px330 plasmid (Addgene, 42230). To perform genomic deletion, a pair of gRNAs containing plasmids were co-transfected into C2C12 cells with screening plasmid pSIREN-RetroQ (Clontech) using Lipotectamine 2000. Cells were selected with 2.5ug of puromycin for 3 days at 48 hours post-trasnsfection. Cells were diluted to 1 cell per well in 96 well plate. Individual colonies were PCR validated.
Growth protocol Mouse C2C12 myoblast cell (CRL-1772) was obtained from American Type Culture Collection (ATCC) and cultured in DMEM medium with 10% fetal bovine serum, 1% penicillin/ streptomycin at 37°C in 5% CO2.
Extracted molecule genomic DNA
Extraction protocol C2C12 cells were crosslinked with 1% formaldehyde at room temperature for 10 minutes, followed by quenching with 0.125M glycine for 10 minutes. Chromatin was fragmented using S220 sonicator (Covaris), followed by incubation with 5ug of antibodies and 50uL Dynabeads Protein G magnetic beads (Life Technologies) at 4°C on rotator for overnight. Anti Ddx5 (ab21696, Abcam) was used in ChIP assay. Beads were washed with 1mL RIPA buffer for 5 times, followed by decrosslink at 65°C for 16 hours and DNA extraction with phenol/chloroform. Immunoprecipitated DNA was resuspended in 50uL of water.
