KS2 Science: How effective are different liquids at blocking

DNA polymerases have previously been used in split-pool protocols, but require handles for specific hybridization, inflating barcode length. Barcodes can also be assembled with DNA ligases which can operate with four or less base pair overhangs 20, 21, 22, 23, 24 (Supplementary Fig. 1a,b). These overhangs ensure specific ligation, since different sequences used in sequential steps prevent improper propagation of reactive stubs remaining from failed ligations in previous rounds. To characterize the process, we measure ligation efficiency in a split pool synthesis reaction, observing > 80% of stubs are ligated per round, such that after three rounds 64% of oligos on the bead are full length (Supplementary Fig. 1c). In contrast, beads fabricated using polymerases achieve just 36% yield after two rounds 17. Thus, our results demonstrate that ligation is more efficient for barcode bead fabrication in split-pool protocols than polymerase extension while also yielding more compact barcodes that reduce sequencing waste.
