Sample GSM4577164 Query DataSets for GSM4577164
Status Public on May 23, 2021
Title sgRNA counts (day 18, venetoclax selection) rep2
Sample type SRA
 
Source name Leukemia cell line (THP1)
Organism Homo sapiens
Characteristics cell line: Paediatric monocytic cell line derived from AML M5 with t(9;11)(q21;q23) translocation
crispr sgrna library: TKOv3
treatment: venetoclax
Treatment protocol half the transduced cells were continuously treated with venetoclax for 18 days (6 passages)
Growth protocol lentiviral pooled CRISPR screening with lentiCRISPRv2-TKOv3; cells grown in RPMI 1640 + 10% FBS and passaged every 72h
Extracted molecule genomic DNA
Extraction protocol QIAamp DNA Blood Maxi Kit (Qiagen)
Sequencing libraries were prepared in two PCR steps, the first to enrich sgRNA regions from the genome, and the second to amplify sgRNA and attach sequencing adapters and indices (based on Aregger, M., Chandrashekhar, M., Tong, A. H. Y., Chan, K. & Moffat, J. in Methods Mol. Biol. 169–188 (2019). doi:10.1007/978-1-4939-8805-1_15)
