WebIn general, the specially designed linear-hairpin variable primer has four functions: (1) it acts as a primer for specifically reverse transcription of the target miRNA; (2) it extends to form a hairpin structure enabling the target miRNA to be recycled; (3) it makes the cDNA long enough for PCR amplification; (4) it contains the same sequence of the reverse primer. WebScorpions PCR primers contain a sequence complementary to an internal portion of the target sequence. LUX PCR Primers These assays employ two DNA primers, one of which is a hairpin-shaped PCR primer with a fluorescent reporter attached near the 3' end, as illustrated in Figure 8. The reporter is quenched by the secondary structure of the hairpin.
