| Product Name | RNA Rapid Isothermal Amplification Kit (Basic) |
| Catalog No. | RESK-0119 |
| Description | A raw-material reagent kit for recombinase polymerase amplification (RPA), developed with recombinase, single-stranded DNA binding protein, and strand-displacing DNA polymerase for isothermal amplification of RNA nucleic acid targets. Only a pair of specific primers and template need to be added to the reaction system for isothermal amplification; the purified amplification product is then analyzed by agarose gel electrophoresis for result interpretation. In RPA, recombinase proteins form complexes with primers that search for homologous sequences on double-stranded DNA. The recombinase strand-exchange activity inserts the primer at the homologous site, and single-stranded binding proteins stabilize the displaced DNA strand. The recombinase is then disassembled so that the primer 3' end is strand-displaced and bound by DNA polymerase, which extends the primer; repeating this cycle exponentially amplifies the target region of the template. |
| Intended Use | For isothermal amplification and rapid detection of RNA targets in research and assay development; widely applicable to in vitro diagnostics, veterinary testing, food safety, biosafety, and agriculture. |
| Principle / Technology | Recombinase polymerase amplification (RPA) with reverse transcription for RNA templates: recombinase proteins form complexes with primers that search for homologous sequences on double-stranded DNA; the recombinase strand-exchange activity inserts the primer at the homologous site while single-stranded binding proteins stabilize the displaced DNA strand. The recombinase is then disassembled, leaving the primer 3' end accessible to a strand-displacing DNA polymerase that extends the primer; repeating this cycle exponentially amplifies the target region. Multiple enzymes participate, including T4 UvsX, T4 UvsY, GP32, Bsu DNA polymerase, and creatine kinase (CK). |
| Detection Method | Agarose gel electrophoresis of the purified amplification product for result interpretation. |
| Sample Type | RNA nucleic acid templates. |
| Performance Range / Specifications | Multi-enzyme system involving T4 UvsX, T4 UvsY, GP32, Bsu DNA polymerase, and CK. Isothermal reaction at 37-42 °C for 10-30 min amplifies trace nucleic acid to a detectable level. Detection sensitivity down to a single copy or tens of copies (or fewer) of RNA. Low instrument dependence; simple operation and straightforward result interpretation. Widely used in in vitro diagnostics, veterinary, food safety, biosafety, and agriculture. |
| Sensitivity / LOD | Down to a single copy or tens of copies (or fewer) of RNA. |
| Specificity | Sequence-specific amplification driven by a pair of specific primers targeting the RNA sequence of interest. |
| Reaction Conditions / Protocol | Isothermal incubation at 37-42 °C for 10-30 min. Add a pair of specific primers and template to the reaction system; after amplification, purify the product and analyze by agarose gel electrophoresis. |
| Components / Formulation | RPA enzyme system including T4 UvsX recombinase, T4 UvsY, GP32 single-stranded DNA binding protein, Bsu DNA polymerase, and creatine kinase (CK), with reverse transcription capability for RNA templates. Primers and template are supplied by the user. |
