hsa-miR-126-3p RCA Padlock Probe

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)

For miRNA 126-3p, we designed two complementary arms, BBa_K4245102, the 3' arm for hsa-miR-126-3p and BBa_K4245109, the 5' arm for hsa-miR-126-3p. 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.
