Design Notes
A padlock probe, which is often 30-150 nucleotides in length, is a single-stranded DNA sequence designed to recognize a specific target sequence. The “arms” of a padlock probe are the ends of the ssDNA that are complementary to a specific target sequence. The middle sequence (the sequence between the arms) can be specifically designed to perform a function once amplified (Nilsson et al., 1994).
Lambert iGEM found three specific miRNAs — hsa-miR-1-3p (BBa_K4245006), hsa-mir-133a-3p (BBa_K4245009), and hsa-miR-208a-3p (BBa_K4245011) — to be upregulated in correlation to CAD (Kaur et al., 2020). For hsa-miR-451a, we designed two complementary arms, BBa_K4245106, the 3' arm for hsa-miR-451a and BBa_K4245113, the 5' arm for hsa-miR-451a. For the reporter, we decided on both BBa_K4245130/BBa_K4245132 the FAM and BHQ1 labeled linear probes, and BBa_K4245134/BBa_K4245135, the DNA fluorescent aptamer split lettuce, due to their frugality and similar wavelength to GFP.
