Diagnostic Devices for Isothermal Nucleic Acid Amplification
Since the development of the polymerase chain reaction (PCR) technique, genomic information has been retrievable from lesser amounts of DNA than previously possible. PCR-based amplifications require high-precision instruments to perform temperature cycling reactions; further, they are cumbersome for routine clinical use. However, the use of isothermal approaches can eliminate many complications...
متن کاملReal-time electrochemical monitoring of isothermal helicase-dependent amplification of nucleic acids.
We described an electrochemical method to monitor in real-time the isothermal helicase-dependent amplification of nucleic acids. The principle of detection is simple and well-adapted to the development of portable, easy-to-use and inexpensive nucleic acids detection technologies. It consists of monitoring a decrease in the electrochemical current response of a reporter DNA intercalating redox p...
متن کاملIsothermal, in vitro amplification of nucleic acids by a multienzyme reaction modeled after retroviral replication.
A target nucleic acid sequence can be replicated (amplified) exponentially in vitro under isothermal conditions by using three enzymatic activities essential to retroviral replication: reverse transcriptase, RNase H, and a DNA-dependent RNA polymerase. By mimicking the retroviral strategy of RNA replication by means of cDNA intermediates, this reaction accumulates cDNA and RNA copies of the ori...
متن کاملIsothermal Amplification Methods for the Detection of Nucleic Acids in Microfluidic Devices
Diagnostic tools for biomolecular detection need to fulfill specific requirements in terms of sensitivity, selectivity and high-throughput in order to widen their applicability and to minimize the cost of the assay. The nucleic acid amplification is a key step in DNA detection assays. It contributes to improving the assay sensitivity by enabling the detection of a limited number of target molec...
متن کاملA molecular predator and its prey: coupled isothermal amplification of nucleic acids.
BACKGROUND A novel approach to the study of in vitro evolution is provided by the investigation of continuous, functionally coupled, amplifying systems. To date, in vitro evolution experiments have focused on issues of mutation and selection. Our work contributes to the new field of in vitro molecular ecology studies in which detailed information about the relationship between sequence changes ...
