Sample GSM2564493 Query DataSets for GSM2564493
Status Public on Jul 20, 2017
Title Croatan_dual_screen_K562_T0_R3
Sample type SRA
 
Source name K562-Cas9 cells
Organism synthetic construct
Characteristics timepoint: T0
library: Croatan dual sgRNA screen library
Treatment protocol Cells were infected with lentivirus harboring sgRNA libraries, with an MOI of 0.3, and were kept in culture for 12 doublings
Growth protocol A375 and K562 cell lines were grown at 37C with 5% CO2 according to ATCC guidelines
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted 2 days after infection (T0) and after 12 doublings (T6) using the QIAamp Blood DNA Midi Kit (Qiagen).
For each sample, sgRNA sequences were extracted from genomic DNA in 8 separate 30-cycle PCR reactions where 2 ug of input DNA was included in each reaction. Illumina adapters where included on the PCR primers for this PCR.
Samples were sequenced on the Illumina MiSeq platform.
