Testa Analytical Solutions eK reports that Dynamic Light Scattering (DLS) can be used as an effective analytical technique for analysing virus particles in solution. A new application report examines four fish viruses incubated under laboratory culture conditions that have the potential to wreak significant economic damage to both recreational and commercially important fish populations. Traditional visual methods of observing virus particles in solution give a snapshot of only a very small and potentially unrepresentative sampling volume. By comparison, the technique of particle analysis using dynamic light scattering yields an ensemble average of particles present in these solutions. Data presented in the report is from DLS measurements made on a NanoBrook ZetaPALS instrument equipped with a BI-MAS accessory to provide particle sizing capability.
