A novel RNA FRET probe that can produce target-dependent signal amplification with the catalysis of RNase H has been developed for detection of rolling circle amplification (RCA) products with greatly improved sensitivity.
Circularizable oligonucleotide probes can detect short DNA sequences with single-base resolution at the site of ligation and can be amplified by rolling circle amplification (RCA) using strand displacing polymerases. A secondary amplification scheme was developed that uses the loop-mediated amplification reaction concurrent with RCA to achieve rapid signal development from the starting circular...
OBJECTIVE Older adults often have trouble adjusting to hearing aids when they start wearing them for the first time. Probe microphone measurements verify appropriate levels of amplification up to the tympanic membrane. Little is known, however, about the effects of amplification on auditory-evoked responses to speech stimuli during initial hearing aid use. The present study assesses the effects...
