Molecular Beacon

The locked hairpin is composed of the sequence of Ochratoxin A (OTA) aptamer, the sequence of RCA primer and the locked sequence. In the absence of OTA, the locked hairpin should be stable as "close status", eliminating nonspecific recognition. In the presence of OTA, the hairpin structure would transform into “open” conformation due to the recognition event between the aptamer and OTA.
