A sensitive duplex-immunocapture-RT-PCR (D-IC-RT-PCR) technique was developed for detection and discrimination of taxonomically distinct Sugarcane streak mosaic virus (SCSMV) and Sugarcane mosaic virus (SCMV) that naturally infect sugarcane. D-IC-RT-PCR was performed using polyclonal antisera for capture of virions. Oligo 5'-d(T)18(AGC)-3' as a common reverse primer for both viruses and virus s...

Timely implementation of antiviral treatment and other public health based responses are dependent on accurate and rapid diagnosis of the novel pandemic influenza A(H1N1) strain. In this study we developed a duplex real-time PCR (RT-PCR) (dFLU-TM) assay for the simultaneous detection of a broad range of influenza A subtypes and specific detection of the novel H1N1 2009 pandemic strain. The assa...

background and aims: certification programs of plant propagating materials rely on faster, cheaper and more importantly sensitive and reliable methods for detection of systemic pathogens as indicated in national and/or international health standards of plant propagating materials. reverse transcription-polymerase chain reaction (rt-pcr) has been documented as an alternative assay for certificat...

We have developed a one-tube reverse transcription (RT)-PCR method using the real-time TaqMan PCR system for the detection of norovirus genogroup I (NV GGI). By introduction of a novel probe based on locked nucleic acid technology, we enhanced the sensitivity of the assay compared to those of conventional TaqMan probes. The sensitivity of the NV GGI RT-PCR was determined by probit analysis with...

BACKGROUND Characterization of fusion gene transcripts in leukemia that result from chromosome translocations provides valuable information regarding appropriate treatment and prognosis. However, screening for multiple fusion gene transcripts is difficult with conventional PCR and state-of-the-art real-time PCR and high-density microarrays. METHODS We developed a multiplex reverse transcripti...

OBJECTIVES An unexpectedly high proportion of children were admitted for severe respiratory infections at the Oslo University Hospital, Ullevål, Norway, during September and October, 2014. In light of the ongoing outbreak of enterovirus-D68 (EV-D68) in North America a real-time RT-PCR for screening of enterovirus and enterovirus D68 was established. DESIGN We developed a duplex real-time RT-P...

The comparison of the gene expression profiles between two subpopulations of melanoma cells (1C8 and T1C3) derived from the tumor of one patient by cDNA array revealed differences in GAPDH and beta-actin gene levels. These two housekeeping genes were up-regulated in invasive T1C3 melanoma cells compared to noninvasive 1C8 cells. Since cDNA array results were not confirmed by conventional RT-PCR...
