WebA high quality RNA sample should have an A 260 /A 280 UV spectrophotometer reading close to 2. It has been observed that an A 260 /A 280 reading of 1.8 suggests there is about 70–80% of protein in the samples—there are many proteins that inhibit both PCR and reverse transcription. Inhibition plot: You can use real-time PCR data from ... WebLocked nucleic acids are modified RNA monomers. The “locked” part of their name comes from a methylene bridge bond linking the 2′ oxygen to the 4′ carbon of the RNA pentose ring (Figure 1). The bridge bond fixes the pentose ring in the 3′-endo conformation. Figure 1. A locked nucleic acid monomer.
