Specifications:
Recombinase Polymerase Amplification (RPA) is a nucleic acid amplification technique that can be carried out at a constant temperature (37–42°C) without the need for a thermal cycler. This kit relies on recombinase (UvsX), single-stranded DNA-binding protein (GP32), and strand displacement DNA polymerase to achieve nucleic acid amplification under constant temperature conditions. Just by designing specific primers and adding the template, the amplification product can be obtained by incubating at 37°C for 10–40 minutes. The product can be detected through electrophoresis, real-time fluorescence (combined with Exo probe), or lateral flow test strips (LFS).
Constant temperature reaction: The reaction can be carried out at 37–42°C, requiring only a simple heating block or water bath, without the need for a PCR machine;
Ultra-fast amplification: The amplification can be completed in 10–40 minutes, much faster than conventional PCR;
Convenient and rapid: It can be combined with colloidal gold test strips to achieve visual judgment by the naked eye, with extremely low dependence on equipment;
Multiple compatibility: Multiple target detections can be achieved simultaneously by using different labeled primers.

Isothermal library amplification (replacing PCR for NGS library construction), on-site rapid detection (for animal diseases, plant pathogens, food safety), bedside rapid diagnosis without PCR instrument, highly specific detection combined with CRISPR-Cas12/13 (SHERLOCK/DETECTR platforms).
A positive control band corresponding to the target was amplified.
1. 污染:操作不规范、样本浓度过高或未分区导致气溶胶污染。需分区实验,紫外灯灭菌,使用核酸清除剂清洁。 2. 试剂失效:引物/探针设计不良或降解,需重新验证探针特异性。 3. 模板问题:RNA模板三级结构抑制逆转录酶,建议先加模板再激活剂,或分别加入管内壁两侧后离心混匀。
The amplification curve shows abnormalities, and there are non-specific bands present.
1. Secondary peak: This is caused by the competition between the polymerase and the exonuclease in the fluorescence experiment, and it does not affect the result interpretation. 2. Excessive baseline: The activator was added too early in the fluorescence-based system, resulting in the degradation of primers/probes by the nucleases.
