Sample GSM4912506 Query DataSets for GSM4912506
Status Public on Nov 08, 2021
Title Donor Mouse 1 baseline
Sample type SRA
 
Source name Donor Mouse 1 baseline
Organism Mus musculus
Characteristics donor mouse: mouse 1
timepoint: Baseline
Treatment protocol Cells were transduced with SPLINTR barcode libraries in polybrene (8.5 mg/mL) via spinfection (90 minutes at 1250 g).
Growth protocol c-Kit positive hematopoietic progenitor cells were cultured in RPMI-1640 medium supplemented with mouse IL-3 (10 ng/mL), human IL-6 (10 ng/mL), mouse SCF (50 ng/mL) 20% fetal bovine serum (FBS), streptomycin (100 ug/mL), penicillin (100 units/mL) and 2 mM glutamax in 5% CO2 at 37 °C.
Extracted molecule genomic DNA
Extraction protocol Viable cells were sorted on the BD FACSAria III directly into Eppendorf tubes. The cells were then washed twice with PBS + 0.04% BSA.
Cells were lysed in 40 uL Viagen lysis buffer containing 0.5 mg/mL Proteinase K (Invitrogen) and split into technical replicates. Barcodes in cell lysate were then amplified following two rounds of PCR using Q5 polymerase (NEB). The first PCR amplified barcode specific DNA and added partial Illumina sequencing primer binding sites. PCR primers containing staggers to account for low sequence diversity during sequencing. In the second round PCR, the sequencing primer binding sites were completed, P5 and P7 flow cell regions were added and samples received a well-specific 8bp dual index (96 different indices in total).

Description KF10BarcodeCPM.txt
Data processing Barcode sequences were extracted from fastq files based on the known constant sequences flanking the random barcodes and subsequently trimmed to remove these regions such that only the random barcode sequences remained.
Barcode containing reads were further filtered to keep only those barcodes that (a) showed a correct upstream constant region (5’- CGATTGACTA-3’), (b) showed the expected barcode pattern (c) did not contain N residues, and (d) possessed an average phred quality of 30 or higher across the length of the barcode.
Barcode reads were then mapped to the respective SPLINTR reference library using bowtie v1.2.2 allowing up to 2 mismatches.
Barcode count data were imported into R v3.6 for further analysis.
