Reverse Primer for RPA of LINC00857
Long intergenic non-protein coding RNA 857 (LINC00857) is a genetic molecule involved in cancer biology, which is identified as one of the most upregulated LINCRNAs in lung cancer. It could lead to resistance to platinum‐induced apoptosis by affecting mRNA stability or promoting its translation. Thus, we chose LINC00857 as a novel prognostic and cancer predictive biomarker. We use this part as the reverse primer to conduct reverse transcription-recombinase polymerase amplification (RT-RPA) of LINC00857, along with its forward primer (BBa_K4308000).
Usage and Biology
In our project, this primer (BBa_K4308001) was used along with its forward primer (BBa_K4308000) for the amplification reactions of LINC00857, in order to perform isothermal amplification reactions with RT-RPA. Using this method, we were able to detect quantities as low as 10-9 nanograms during 30 minutes. The expected amplified product length is about 150 bp.

Characterization
1. Experimental verification of RT-RPA
The results of the above RPA pre-experiment were better, so we replaced our target gene LINC00857 for reverse transcription-recombinase polymerase amplification (RT-RPA). After RT-RPA amplification, we carried out 3% agarose gel electrophoresis to verify the amplification results. As can be seen in Figure 2, compared with negative control, our product has obvious bands, which also confirms the validity of the primer.
