Virus Purification & Concetration

Question 1

Describe the 4 different ways to purify viruses.

Answer 1

1. Ultracentrifugation
   -efficiently sediment viruses
   -used for conc & purification of viruses
2. Rate zonal centrifugation
   -under centrifugal force, particles move at diff rates depending on their mass
3. isopycinc centrifugation
   -buoyant or equilibrium separation
   -particles sep based on their buoyant density
4. Virus purification with membrane chromatography
