Sample GSM2135707 Query DataSets for GSM2135707
Status Public on Mar 07, 2018
Title H2AZ_CHIPSeq_R1881
Sample type SRA
 
Source name 22Rv1_H2AZ_CHIPSeq_R1881
Organism Homo sapiens
Characteristics cell line: 22Rv1
cell type: prostate cancer cells
treated with: R1881
chip antibody: H2A.Z(ab4174,abcam)
Treatment protocol 22Rv1 cells were transfected with non-target siRNA (designated as ARFL+/ARVs+), siRNA targeting ARV1/3/4/7 (designated as ARFL+/ARVs-) or siRNA targeting AR exon7 (designated as ARFL-/ARVs+), cultured with charcoal-stripped serum (CSS) medium for 72 hours, then treated with or without androgen (R1881) .
Growth protocol Prostate cancer cells were cultures (typically 2–3 × 106 cells into a T75 flask) in RPMI 1640 medium (Gibco, Unite State) with charcoal-stripped (steroid depleted) serum (CSS).
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody.
Libraries were prepared according to Illumina's instructions accompanying the DNA Sample Kit (Part# 0801-0303). 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. Libraries were sequenced on the Illumina HiSeq 2000 following the manufacturer's protocols.
