Simple sequence repeat (SSR markers or microsatellites), based on the specific PCR amplification of DNA sequences, are becoming the markers of choice for molecular characterization of a wide range of plants because of their high polymorphism, abundance, and codominant inheritance. Different methods have been used for the analysis of the SSR amplified fragments being submarine agarose electropho...
Isothermal nucleic acid amplification of target RNA or DNA sequences is accomplished by the simultaneous enzymatic activity of AMV reverse transcriptase, T7 RNA polymerase and RNase H. Amplification factors of the nucleic acid sequence based amplification (NASBA) method range from 2 x 10(6) to 5 x 10(7) after 2.5 h incubation at 41 degrees C. During NASBA there is a major accumulation of specif...
BACKGROUND Multiplexing technologies, which allow for simultaneous detection of multiple nucleic acid sequences in a single reaction, can save a lot of time, cost and labor compared to traditional single reaction detection methods. However, the multiplexing method currently used requires precise handiwork and many complicated steps, making a new, simpler technique desirable. Oligonucleotides co...
A simple isothermal nucleic-acid amplification reaction, primer generation-rolling circle amplification (PG-RCA), was developed to detect specific nucleic-acid sequences of sample DNA. This amplification method is achievable at a constant temperature (e.g. 60 degrees C) simply by mixing circular single-stranded DNA probe, DNA polymerase and nicking enzyme. Unlike conventional nucleic-acid ampli...
Human immunodeficiency virus (HIV) rapid variant mutations challenges diagnostic assays. Our variant-tolerant isothermal nucleic acid based amplification technique enables reliable detection at the point-of-care.
