Real-time nucleic acid sequence-based amplification using molecular beacons for detection of enterovirus RNA in clinical specimens.
Real-time nucleic acid sequence-based amplification (NASBA) using molecular beacon technology (NASBA-beacon) was compared to standard NASBA with postamplification hybridization using electrochemiluminescently labeled probes (NASBA-ECL) for detection of enteroviruses (EV) in 133 cerebrospinal fluid and 27 stool samples. NASBA-ECL and NASBA-beacon were similar in sensitivity, detecting 55 (100%) ...
متن کاملSensitivity and Specificity of Nucleic Acid Sequence-Based Amplification Method for Diagnosis of Cutaneous Leishmaniasis
Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
متن کاملRapid enterovirus RNA detection in clinical specimens by using nucleic acid sequence-based amplification.
Enterovirus (EV) detection by nucleic acid sequence-based amplification was compared with EV isolation in cell culture. The NucliSens Basic kit (bioMerieux) was utilized for RNA detection. For virus isolation, samples were inoculated into MRC-5, primary rhesus monkey kidney, A549, rhabdomyosarcoma, and/or Buffalo green monkey kidney cells.
متن کاملPrinciples of quantitation of viral loads using nucleic acid sequence-based amplification in combination with homogeneous detection using molecular beacons.
For quantitative NASBA-based viral load assays using homogeneous detection with molecular beacons, such as the NucliSens EasyQ HIV-1 assay, a quantitation algorithm is required. During the amplification process there is a constant growth in the concentration of amplicons to which the beacon can bind while generating a fluorescence signal. The overall fluorescence curve contains kinetic informat...
متن کاملMolecular Beacons of Xeno-Nucleic Acid for Detecting Nucleic Acid
Molecular beacons (MBs) of DNA and RNA have aroused increasing interest because they allow a continuous readout, excellent spatial and temporal resolution to observe in real time. This kind of dual-labeled oligonucleotide probes can differentiate between bound and unbound DNA/RNA in homogenous hybridization with a high signal-to-background ratio in living cells. This review briefly summarizes t...
