Concentration and Size of Viruses and Virus-like Particles

Accurate concentration for virus and virus-like particles can be determined by multi-laser nanoparticle tracking analysis due to the fact they are nanoparticles. Other biologically relevant materials will have sizes that are close to those of viruses, whether they are protein aggregates that provoke an unwanted immune response or exosomes with a similar size and do not provoke an immune response.

In this webinar, Dr. Jeff Bodycomb will discuss the use of multi-laser nanoparticle tracking analysis (NTA) to determine the size distribution and concentration of these species, the latter which is correlated to viral infectivity.
