Virus Quantification using the nCS1^TM

Better science:

For measuring the infectivity of viruses, testing the immunogenicity of different viral preparations, and almost any down-stream analysis, accurate virus concentration measurements are critical for performing well-controlled experiments.

A retroviral drug product was serially diluted and the concentration measured as a function of size showing the excellent concentration linearity of the nCS1^TM:

More and more researchers are choosing the nCS1^TM for virus quantification because it is fast and easy to use and delivers a more accurate analysis of their virus samples than they can obtain using any other method.

Higher purity of viral preparations

Accurate and high-resolution particle concentration measurements enable direct quantification of the purity of virus preparations. Because the nCS1^TM measures all types of particles in the sample, it can be used to quantify impurities and other non-viral particles in a given preparation.

The figure below shows measurements of a virus preparation at progressive stages of purification. Clearly purification step 2 significantly enriches for the target virus, as evidenced by the peak in the size distribution.
