Abstract: Methods for rapidly and accurately detecting genetic material from hop latent viroid RNA (HLVd) that combines reverse transcription loop-mediated isothermal amplification (RT-LAMP) technology with specific oligonucleotide primers, fluorophore-labeled oligonucleotide primers, quencher-conjugated oligonucleotide primers, pH buffers, and enzymes, are described. The methods include at least one internal positive control targeting sequence, for minimizing false positive and false negative results, thereby allowing more certain interpretation of the results. The reaction can be performed at a single elevated temperature, can be completed in 1-1.5 hours, and the results can readily be interpreted by visually observing the fluorescence color of the reaction using ultraviolet light, or by using an electronic image acquisition system for viewing fluorescence results from one or more reactions.

Abstract: Methods and a kit for detection of genetic material from SARS-CoV-2 that combines reverse transcription loop-mediated isothermal amplification (RT-LAMP) technology with specific oligonucleotide primers, fluorophore-labeled oligonucleotides, quencher technology, buffer components, enzymes, and enzyme ratios chosen to minimize false positive and false negative results, are described. The method includes internal positive control targeting sequences, allowing more certain interpretation of the results. The reaction can be performed at a single elevated temperature, can be completed in 1-2 hours, and the results can readily be interpreted by visually observing the fluorescence color of the reaction using ultraviolet light.
