Webligation of sequencing adapters designed with 3′ T-overhangs, not present in previous ligation-based library prep kits (Figure 1A). A by-product of this approach is that the first cycle of sequencing Read 1 and Read 2 will be derived from the T-overhang in the adapter and detected as a “T” (Figure 1B), and not from the DNA being sequenced.
