Duplex-Seq
Duplex Sequencing
Duplex-Seq is a tag-based, error-correction method to improve sequencing accuracy (Schmitt et al., 2012). In this method, adapters (with primer sequences and random 12 bp indexes) are ligated onto the template and amplified using PCR. Deep sequencing provides consensus sequence information from every unique molecular tag. Based on the molecular tags and sequencing primers, duplex sequences are aligned, determining the true sequence on each DNA strand. The method is estimated to be > 10,000-fold more accurate than conventional NGS (Ahn et al., 2015). A targeted version of duplex sequencing includes 2 rounds of capture to yield read depth as high as 1,000,000x (Schmitt et al., 2015)
Advantages:
- Can detect a single point mutation among > 107 sequenced nucleotides(Schmitt et al., 2012), (Schmitt et al., 2015)
- Very low error rate due to duplex tagging
- PCR amplification errors can be detected and removed from analysis
- No additional library preparation steps after addition of adapters
Disadvantages:
