Targeted sequencing of potential CRISRP/Cas9 off-target editing sites in modified human CD34+ Haematopoietic Stem Cells


ABSTRACT: We report the use of short biotinylated oligonucleotides for the targeted pulldown of potential CRISPR/Cas9 off-target loci in condition and control to measure the frequency of off target editing Overall design: NG Capture-C was used to investigate the Potential off-target CRISPR/Cas9 loci. NG Capture-C combines 3C library preparation with oligonucleotide capture for the desired viewpoint restriction fragments. Potential off-target CRISPR/Cas9 loci were identified using the Sanger tool (http://www.sanger.ac.uk/htgt/wge/find_off_targets_by_seq) and 70bp oligonucleotides designed for target-pulldown. Whole genome amplified (WGA) DNA from edited clones from two editing strategies was pooled and indexed. Indexed WGA DNA was then pulled down in two rounds of hybridization with biotinylated oligonucleotides and streptavadin beads to enrich for putative off-target editing loci.

β-Thalassemia is one of the most common inherited anemias, with no effective cure for most patients. The pathophysiology reflects an imbalance between α- and β-globin chains with an excess of free α-globin chains causing ineffective erythropoiesis and hemolysis. When α-thalassemia is co-inherited with β-thalassemia, excess free α-globin chains are reduced significantly ameliorating the clinical severity. Here we demonstrate the use of CRISPR/Cas9 genome editing of primary human hematopoietic ste  ...[more]
