Design Notes

For the padlock probe (PLP) design, part of the reverse complement of the miRNA makes up each end of the padlock probe. To determine where the reverse complement is split properly, we determined the annealing temperatures of each arm through SnapGene. To allow successful hybridization and maximize the binding efficiency of the miRNA and the padlock arms, the arms need to have the same annealing temperature. Furthermore, we added a phosphate group modification to the 5’ end of the padlock sequence to allow ligation by SplintR ligase (Jonstrup et al., 2006).

Figure 1. The arrangement of the padlock probes and their target miRNAs.


Additionally, the alignment of the 5’ and 3’ ends is essential to determine where each part of the padlock and its arms matches up to the target miRNA (Liu et al., 2013). The miRNA strand hybridizes antiparallel to the padlock arms (see Fig. 1) Therefore, the 5’ end of the miRNA will end up overlapping the 5’ PLP arm, and the 3’ end of the miRNA will end up overlapping the 3’ PLP arm (Liu et al., 2013).
