This study established a constant-temperature fluorescence quantitative detection method, combining loop-mediated isothermal amplification (LAMP) with molecular beacons. The advantages of LAMP are its convenience and efficiency, as it does not require a thermocycler and results are easily visualized by the naked eye. However, a major disadvantage of current LAMP techniques is the use of indirec...
This study was aimed to rapidly identify and differentiate two main pathogens of the Mycobacterium tuberculosis complex: Mycobacterium tuberculosis subsp. tuberculosis and Mycobacterium bovis by a modified loop-mediated isothermal amplification (LAMP) assay. The reaction results could be evaluated by naked eye with two optimized closed tube detection methods as follows: ...
The success of real-time PCR (qPCR) analysis is partly limited by the presence of inhibitory compounds in the nucleic acid samples. For example, humic acid (HA) from soil and aqueous sediment interferes with amplification and also quenches the fluorescence of double-stranded (ds) DNA binding dyes, thus hindering amplicon detection. We aimed to counteract the HA fluorescence quenching effect by ...
Mycoplasmas are the smallest and simplest organisms known. They form a large group of bacteria that can infect humans, animals, and plants. Even though several techniques have been proposed to enumerate mycoplasmas in broth medium, the determination of mycoplasma growth still remains a difficult task. The potential of using flow cytometry (FC) for rapidly estimating several species of mycoplasm...
In recent years, the studies of RNA and its use for development based vaccines have increased drastically. Although cyanine dyes are commonly used probes studying nucleic acids, in a wide range applications, there is still growing need better brighter dyes. To meet this demand, we systematically studied structure SYBR green-related to gain deeper understanding their interactions with biomolecul...
A novel nucleic acid stain, SYBR Gold, was used to stain marine viral particles in various types of samples. Viral particles stained with SYBR Gold yielded bright and stable fluorescent signals that could be detected by a cooled charge-coupled device camera or by flow cytometry. The fluorescent signal strength of SYBR Gold-stained viruses was about twice that of SYBR Green I-stained viruses. Di...
