Sample GSM822388 Query DataSets for GSM822388
Status Public on Mar 25, 2012
Title LNCaP DHT DNaseI
Sample type SRA
 
Source name prostate cancer cells
Organism Homo sapiens
Characteristics cell line: LNCaP
cell type: prostate cancer cells
passages: 14-17
treatment: DHT
sample type: DNase-seq
Treatment protocol Cells were cultured in RPMI 1640 supplemented with 10% charcoal-stripe FBS for 3 days, and then treated with DHT or Ethanol for 4 hours for prostate cancer cells, treated with E2 or Ethanal for 45mins for breast cancer cells
Extracted molecule genomic DNA
Extraction protocol H3K4me2 ChIPed DNA or the size selected DNase I digested DNA was used for library preparation. 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 18 cycles and library fragments of ~220 bp (for H3K4me2 ChIP-seq) or 200~300bp (for DNase-seq) (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 Genome Analyzer or HiSeq machine following the manufacturer's protocols.
