Sample GSM7906252 Query DataSets for GSM7906252
Status Public on Apr 03, 2024
Title P18_ref_8
Sample type SRA
Source name Blood
Organism Homo sapiens
Characteristics tissue: Blood
cell line: GM24385
cell type: B-Lymphocyte
genotype: WT
treatment: Nucleofection of Cas9 and gRNA targeting the REF or ALT alelle
Extracted molecule genomic DNA
Extraction protocol The gDNA of lymphoblastoid cells nucleofected with RNPs was extracted 3 days after CRISPR delivery using the Qiagen Blood and Tissue Kit (Qiagen 69506) according to the manufacturer’s instructions.
Approximately 100ng of gDNA from each sample was used for locus amplification using the primers listed in Supplementary Table 8. Amplicon libraries were generated as described elsewhere 65 with the following modifications: a first round of amplification using the NEBNext UltraII Q5 Master Mix (M0544) was performed with 33 cycles. The amplified DNA was purified using a 1× volume of DNA AMPure XP beads (Beckman Coulter A63987) and the entire purified product was used for a second round of PCR with primers containing p5 and p7 sequences for Illumina sequencing (Supplementary Table 8). Amplicons were pooled and sequenced in a MiniSeq sequencer with the MiniSeq Mid Output Kit (Illumina FC-420-1004) in single-read mode and 150 cycles.

Supplementary files format and content: TAR of tab-separated files showing the number of modifications for positions in the quantification window of the amplicon. The first row shows the amplicon sequence in the quantification window, and successive rows show the number of reads with insertions (row 2), insertions_left (row 3), deletions (row 4), substitutions (row 5) and the sum of all modifications (row 6). Additionally, the last row shows the number of reads aligned.
