Abstract

Loop-mediated isothermal amplification (LAMP), a nucleic acid amplification technology, has been characterized as having a short reaction time while generating a large amount of DNA product under isothermal conditions. Here, we found that LAMP is able to amplify more than one target simultaneously by using a mixture of human immunodeficiency virus-1, hepatitis B virus, and hepatitis C virus primers, a process we have named target mixed LAMP. Target mixed LAMP and detection can be performed in less than 1 h. In this study, we also used target mixed LAMP to successfully amplify GAPDH, gamma-actin, TATA box binding protein, and haptoglobin from pooled cDNA derived from mouse tissues. Furthermore, using eight plasmid vectors as templates, target mixed LAMP is able to amplify all targets simultaneously. These findings reveal the usefulness of LAMP for the diagnosis of infectious disease as well as for conducting gene expression analysis.
