Sample GSM2140800 Query DataSets for GSM2140800
Status Public on Apr 17, 2017
Title Cis_3
Sample type SRA
Source name H1 POU5F1-IRES-eGFP
Organism Homo sapiens
Characteristics cell type: H1 POU5F3-eGFP reporter cells
Treatment protocol Regular hESC culture without any special treatment.
Growth protocol Cells were cultured at 37 celsius degree in 5% CO2, in Essential 8 media (Stemcell Technologies).
Extracted molecule genomic DNA
Extraction protocol For Samples 1-10, genomic DNA was extracted from H1 POU5F1-eGFP reporter cells after CREST-seq screen. For Sample 11, the plasmid DNA was extracted from E coli using Qiagen Giga prep kit.
The genomic DNA (samples 1-10) or CREST-seq plasmid DNA library (Sample 11) was PCR amplified with the following primers containing illumina TruSeq adaptor sequence. Forward primer: AATGATACGGCGACCACCGAGATCTACACTCTTTCCCTACACGACGCTCTTCCGATCTctTGTGGAAAGGACGAAAC; Reverse Primer: CAAGCAGAAGACGGCATACGAGATAAGGCCACGTGACTGGAGTTCAGACGTGTGCTCTTCCGATCTttttAACTTGCTATTTCTAGCTCTAAAAC. The PCR product was Gel purified, quantified and subjected to sequencing.

Description eGFP-/POU5F+ cells, sorted from H1 POU5F1-eGFP reporter cells after CREST-seq screen, replicate 4
Data processing MAGeCK, a model-based analysis of genome-wide CRISPR knockout method, was applied to estimate for each dual-sgRNA the statistical significance of read count enrichment in the experimental samples versus the control samples.
Next, we partitioned the screened region (chr6:30,132,134-32,138,339) into a set of non-overlapping bins of the same length (100bp), and a bin is considered functional if many of the dual-sgRNAs cover it rank near the top of the sorted dual-sgRNAs list.
We then employed Robust Rank Aggression (RRA) (ref) algorithm to identify significant bins.
P-value is finally adjusted to FDR using Benjamini approach. A bin is predicted as significant if its FDR is smaller than given threshold.
