hsa-miR-320b Probe 2
Two DNA probes, one with 5’ phosphorylation, bind to the miRNA, and are ligated together by DNA ligase. Then, primers are added, with DNA polymerase, and complementary strands to the ligated probes are synthesised. Then, RPA can take place: primers, associated with recombinase protein so they can dislodge the strands, replicating them in a similar method to PCR, but as no heat cycles are required to break up the strands, the process can take place isothermally.
In order for the miRNA to be detected, we decided to use ‘asymmetric RPA’: an excess of forward primers are added (usually 5x the amount), so an excess of the strand that was originally miRNA form, so there is now ssDNA with the miRNA code in DNA. This can be detected by our toehold switches.
