Measuring the Particle Size and Concentration of Adeno-Associated Virus using Nanoparticle Tracking Analysis
31 Oct 2016This whitepaper describes the characterization of gold-labeled Adeno-Associated Virus (AAV) and other small viruses by Nanoparticle Tracking Analysis (NTA). It details the method of gold-labelling the virus particles followed by using the NanoSight from Malvern Instruments to utilizes the properties of both light scattering and Brownian motion to obtain the particle size distribution of virus in liquid suspension. The paper concludes that this method can directly measure AAV particle concentration in a matter of hours.

MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
