The CRISPR/Cas9 technology is delivering superior genetic models for fundamental disease research, drug screening, therapy development, rapid diagnostics, and transcriptional modulation. Although CRISPR/Cas9 enables rapid genome editing, several aspects affect its efficiency and specificity including guide RNA design, delivery methods, and off-targets effects. Diagenode has developed strategies to overcome these common pitfalls and has optimized CRISPR/Cas9 genome editing specificity
