![]() ![]() The central elements of EXPAR design are (1) a DNA trigger oligonucleotide that is either the target molecule or is produced by a target molecule, (2) a single-stranded DNA template and (3) polymerase and nickase enzymes. Exponential amplification reaction (EXPAR) is a popular isothermal DNA amplification method that exponentially replicates short oligonucleotide triggers. Identification of specific DNA or RNA sequences in these situations could inform medical professionals and potentially curb health crises. These reactions can even be run without electricity, which is particularly attractive for point of care and limited resource molecular diagnostics. ![]() Isothermal DNA amplification reactions that require less energy, time and equipment than PCR have become an increasingly popular alternative for molecular detection. ![]() While polymerase chain reaction (PCR) provides a gold standard for accuracy and sensitivity of nucleic acid detection, it requires complex laboratory equipment and trained personnel. These mechanisms can potentially illuminate the behaviour of EXPAR as well as other nucleic acid amplification reactions.ĭNA amplification technologies are a cornerstone of molecular diagnostics. The reaction mechanisms are (i) positively cooperative multistep binding spurred by two trigger binding sites on the template (ii) gradual template deactivation (iii) recycling of deactivated templates into active templates and (iv) polymerase sequestration. Furthermore, we show that three of these mechanisms are necessary to reproduce biphasic experimental results. Here we present the first mathematical model of UDAR based on four reaction mechanisms and show the model can reproduce the experimentally observed biphasic behaviour. This ultrasensitive DNA amplification reaction (UDAR) shows high-gain, switch-like DNA output from low concentrations of DNA input. A recent modification of this technique using an energetically stable looped template with palindromic binding regions demonstrated unexpected biphasic amplification and much higher DNA yield than EXPAR. Exponential amplification reaction (EXPAR) is a popular isothermal DNA amplification method that exponentially amplifies short DNA oligonucleotides. This can be beneficial to other community members reading this thread.Isothermal DNA amplification reactions are a prevalent tool with many applications, ranging from analyte detection to DNA circuits.
