Sample GSM6631359 Query DataSets for GSM6631359
Status Public on Jul 14, 2023
Title human library K562 cells
Sample type SRA
 
Source name CML
Organism Homo sapiens
Characteristics cell type: K562
time point: n/a
Treatment protocol K562 and MLLAF9 Cas9 cells (100x10^6 per cell line) were infected with the pooled lentiviral sgRNA libraries at a multiplicity of infection of 0.3. Infected cells were selected with 2ug/ml puromycin for 72hrs, commencing 48hrs after transduction. ~ 100x10^6 cells were fixed/sonicated and ChIP performed at day 6 (H3K4me3) and day 9 (H3K79me2).
Growth protocol Cells were cultured in RPMI-1640 supplemented with 2mM Glutamax, 100IU/ml Penicillin, 100 ug/ml Streptomycin and 10%HI-FCS in 5% CO2 37degrees.
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted using Blood and tissue genomic DNA kit, Qiagen
One-step PCR was performed, containing adaptors for Illumina sequencing.
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NextSeq 500
 
Description human sgRNA library
Custom targeted epigenetic library
Data processing Bcl2fastq (Illumina) was used to convert BCL files to Fastq files
Reads were trimmed to remove adapter with fastx clipper or cutadapt
Trimmed reads were aligned to the reference sgRNA library with bowtie2
After filtering to remove multi-aligning reads, the read counts were computed for each sgRNA.
The RSA algorithm was used to rank the genes for which targeting sgRNA were significantly enriched in the sorted populations compared to the control unsorted populations grown in parallel.
Supplementary files format and content: Guide Counts file
Library strategy: CRISPR-seq
