Virus Counter For Virus Quantification
Virus particles, also known as virions, consist of either DNA or RNA molecules surrounded by a capsid comprised of proteins. Generally, virus particles can be considered as a type of functional nanoparticle, the size of which can range from several tens to hundreds of nanometers. For a long time, electron microscopy (EM) has been the major tool for providing valuable information about single virus particles due to its direct and accurate visualization of viruses. With the development of technologies or adapted from other fields, numerous technologies and methods have been emerging for suitable characterization of virus particles. These technologies not only afford real-time quantification of physical virus particles, but also supply other additional information.
Creative Proteomics is committed to providing a series of inventive services according to the specific needs of our customers all over the world. Here, we are glad to offer virus counter (VC), a powerful tool that has the capability to conduct direct, biologically-specific quantification of viruses in minutes.
Virus Counter (VC) - a robust tool for virus quantification in liquid samples.
Virus counter (VC) is a personalized device for virus quantification in liquid samples, which is developed from flow cytometry. Based on the fluorescent dyes stain the specific proteins and nucleic acids of virus, the method can count viral particles accurately. According to the number of positive particles generating in both channels and the sample flow rate, the particle concentration of virus is finally calculated. Besides, the staining process is non-specific, no requirement for target-specific reagents, such as fluorescence-labelled antibodies for conventional flow-cytometry methods. Therefore, the measurement method relying on the labelling is rapid, reliable, and cost-effective, having the capability of real-time monitoring of virus concentration. Nowadays, VC has been widely utilized to quantify multiple viruses, involving matrix purity levels as well as virus concentrations. These viruses include adenovirus, coronavirus, influenza virus, respiratory syncytial virus (RSV) and so on.
