Investigators at College of Animal Science and Technology Describe Findings in DNA Research

February 11, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on DNA Research is the subject of a report. According to news reporting out of Daqing, People's Republic of China, by NewsRx editors, research stated, "A novel nanoparticle-assisted polymerase chain reaction (nanoPCR) assay to detect porcine parvovirus (PPV) is described here. Primers for this assay were designed based on the conserved region of the nonstructural protein 1 (NS1) gene of PPV, which encodes one of the nonstructural proteins."

Our news journalists obtained a quote from the research from the College of Animal Science and Technology, "The sensitivity of the PPV nanoPCR assay was measured by using diluted recombinant plasmids in which the PPV NS1 gene had been inserted. The detection limit was 5.6 x 10(1) copies mu l(-1) for the PPV nanoPCR assay vs 5.6 x 10(3) copies mu l(-1) for conventional PCR assay. The results showed that the sensitivity of PPV nanoPCR assay was 100 times higher than that of conventional PCR assay. The PPV nanoPCR assay produced 142-bp product as expected when amplifying PPV DNA, while produced nothing when amplifying the DNA or cDNA of the following viruses: swine encephalomyocarditis virus, classical swine fever virus, porcine pseudorabies virus, porcine reproductive and respiratory syndrome virus, porcine teschovirus and porcine circovirus type II."

According to the news editors, the research concluded: "PPV was detected in 108 of 109 clinical swine samples from Heilongjiang, Jilin and Henan provinces using the nanoPCR assay, and the results were confirmed by sequencing."
