Virus Quantification using the nCS1TM


Accurate Viral Titer in Minutes

Conventional methods for quantifying virus such as live biological titer can take days to return results. The modern fast pace of research and current examples such as COVID-19 necessitate faster measurements. Researchers in many areas of virus research including basic virology, gene therapy, and epidemiology are looking for more modern approaches for measuring virus.

Spectradyne's nCS1TM delivers accurate viral particle counts in just a few minutes using Microfluidic Resistive Pulse Sensing (MRPSTM). The technology is fast, easy to adopt and employs disposable microfluidic cartridges for analysis — and it only requires a few microliters of your precious sample for analysis.

nCS1TM key features for virus quantification:

  • Total virus particle count in minutes
  • Disposable analysis cartridges — no laborious cleaning
  • Only uses 3 microliters sample required

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 nCS1TM:

virus dilution

Serial dilutions of a retroviral drug product accurately quantified by Spectradyne's nCS1TM.

More and more researchers are choosing the nCS1TM 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 nCS1TM 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.
