| Title |
HEK293T cells, SpACE_HEKsite2_Rep1 |
| Sample type |
SRA |
| |
|
| Source name |
HEK293T
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: HEK293T
treatment: SpACE
guide rna (grna): HEKsite2
gfp: All GFP
replicate: 1
|
| Treatment protocol |
Transfections were performed using 50ug of transfection quality plasmid DNA (Qiagen Maxiprep), using 37.5ug of base editor plasmid co-translationally encoding P2A-EGFP or variants thereof and 12.5ug of gRNA plasmids. 6-7x10E6 HEK293T cells were seeded into TC-treated 150mm plates 18-24h prior to transfection to yield ~60-80 % confluency on the day of transfection. Cells were transfected using 150uL TransIT-293 (HEK293T, Mirus) reagents per plate, according to the manufacturers’ protocols (mixing DNA and reagent in 5mL Optimem, 30min incubation). GFP positive cells were sorted 36-40h after transfection after doublet-exlusion and gating for the cell population on a BD FACSARIA II.
|
| Growth protocol |
HEK293T cells (CRL-3216, obtained from ATCC) were grown in culture using media consisting of DMEM (Gibco) supplemented with 10% FBS (Gibco) and 1% penicillin-streptomycin (Gibco). Cells were used for experiments until passage 20. Cells were passaged at ~80% confluency every 2-4 days to maintain an actively growing population and avoid anoxic conditions. Cells were tested for mycoplasma bi-weekly.

| Data processing |
RNA sequencing data was aligned to the human reference genome (GRCh38/hg38) using STAR using a basic two-pass alignment strategy. Aligned reads were filtered for those reads that were uniquely mapping using the --outFilterMultimapNmax 1 flag.
Variants associated with BE treatment were called using the GATK best practices pipeline using GATK 3.8.1 and Picard 2.7.
No samples were excluded from bioinformatics analyses.
