The loop of the Scorpions probe includes a … WebHow Uni-Probe Scorpions ® Probes Work. The Scorpions ® Uni-Probe consists of a single-stranded bi-labeled fluorescent probe sequence held in a hairpin-loop conformation with a 5’ end reporter and an internal quencher directly linked to the 5’ end of a PCR primer via a blocker. The blocker prevents the polymerase from extending the PCR primer.
