Abstract
With genetically modified (GM) food circulating on the market, a rapid transgenic food screening method is needed to protect consumer rights. The on-site screening efficiency of GM food testing is low. We report rapid sample-to-answer detection of GM papayas with loop-mediated isothermal amplification (LAMP) and a compact, portable, integrated microfluidic platform using microfluidic lab-on-a-disc (LOAD). GM samples were differentiated from non-GM papaya, based on the detection of a specific GM (P-35S (Cauliflower mosaic virus 35S promoter)) and non-GM DNA marker (papain) in 15 min. The detection limits for DNA and juice from papaya were 10 pg/µL and 0.02 µL, respectively. Our LOAD platform is a simple and robust solution for GM screening, which is anticipated to be a foundation for on-site testing of transgenic food.

Abstract
This article is referred to research article entitled "Whole genome sequence analysis of unidentified genetically modified papaya for development of a specific detection method" (Nakamura et al., 2016) [1]. Real-time polymerase chain reaction (PCR) detection method for unauthorized genetically modified (GM) papaya (Carica papaya L.) line PRSV-YK (PRSV-YK detection method) was developed using whole genome sequence data (DDBJ Sequenced Read Archive under accession No. PRJDB3976). Interlaboratory validation datasets for PRSV-YK detection method were provided. Data indicating homogeneity of samples prepared for interlaboratory validation were included. Specificity and sensitivity test data for PRSV-YK detection method were also provided.
