Panel B. Comparison of guide representation in the plasmid library and transduced cells.


±×¸² 4. Identification and analysis of sgRNAs isolated from cells after a 6-thioguanine (6-TG) screen.
Panel A. sgRNA representation was compared between the original plasmid library population used to make the lentivirus preparation and the resulting transduced, selected and non-selected cell populations. All four sgRNAs for HPRT (red dots) and NUDT5 (black dots) were enriched in the 6-TG-selected population (blue dots). The representation of these sgRNAs in the plasmid library (gray) and transduced, non-selected population (orange) is also shown.
Panel B. After selection, the sgRNA representation was shifted in response (blue) to 6-TG. Individual sgRNAs that were enriched are highlighted within this correlation (red and orange dots). Inset shows fold-enrichment of the four sgRNAs for the HPRT gene as compared to the non-selected population.
