Evaluation of Viral Genome Copies Within Viral Factories on Different DNA Viruses
2018
SummaryThis article describes a simple method of measuring the number of viral genomes within viral factories. For this purpose, we use three DNA viruses replicating in the cytoplasm of the infected cells: wild-type African swine fever virus (ASFV)-Georgia 2007, culture-adapted type ASFV-BA71V, and Vaccinia virus (VV). The measurements are conducted in three steps. In the first step, after DNA staining, we evaluate Integrated Optical Density (IOD) of total DNA for each viral factory. The second step involves the calculations of the mass of DNA in the viral factories in picograms (pg). And, in the third step, by dividing the mass of DNA within viral factory by the weight of a single viral genome, we obtain the number of viral genomes within the factory.
