Superior Viraloff® Antiviral Technology
four) The supernatant (eleven lμl) or virus only control (1/10 (v/v) dilution in infection media) was added to the primary row of wells (MDCK cells in a ninety six-well plate). All supernatant and virus solely controls had been plated in quadruplicate and titrated 10- fold down the plate. Polystyrene sulphonic acids may be appropriate, for instance a commercially obtainable plystyrene sulphonic acid in the form of its sodium salt out there underneath the name Flexan™ II with a molecular weight of around a hundred and twenty,000 could also be suitable.
The position of these antivirals in a pandemic may be limited because of the time and price involved in manufacturing and the present restricted supply. With the recent news of a possible H5N1 pandemic the need to stop any opportunities of transmission of the virus between avian species has risen. If proved efficient in additional analyses, the expertise could provide an additional layer of safety against deadly viruses over time.
