Rapid Virus Quantification
Products from ViroCyt, now part of Sartorius Stedim Biotech, are leading the field of rapid virus quantification. Our goal is to provide the tools that deliver meaningful improvements to mission critical processes, where viruses play a significant role.
- Vaccine production
- Protein expression
- Viral therapeutics
- Antiviral development
ViroCyt has developed a novel approach enabling direct, biologically-specific quantification of viruses in minutes rather than the days or weeks required by more traditional methods. Virus samples are labeled with specifically-developed reagents in a no wash assay. After a 30 minutes incubation period samples are ready for analysis in the Virus Counter® instrument. The purpose-build platform enables quantification of total virus particles in three minutes per the sample, giving users real-time insights into viral titers. The growing list of products includes kits to detect Lentivirus, Adeno-Associated Virus, Baculovirus and Influenza.
Virus Analytics Products for Rapid Virus Quantification
Virus Counter® 3100
The Powerful Tool for Virus Quantification
A novel approach for determining total virus particle concentration that provides precise results in minutes, not days. Get a quantitative picture of viral growth that’s simple, compliant and cost-effective with:
- Focus: The first and only automated technology specifically developed to rapidly quantify intact virus particles
- Speed: Results in minutes, not days or weeks required for other methods
- Reliability: Rugged design for industrial settings, including 21 CFR Part 11-capable software for GMP environments
- Versatility: Multiple detection systems available
Meet the Virus Counter® Platform
Rapid, Direct, Biologically Relevant Virus Quantitation
The Virus Counter® platform is in use by leading companies, regulatory agencies, and research institutes around the world. Why? A growing body of evidence demonstrates that noninfective particles are of biological importance and can Impact both in vitro and in vivo studies. Infectivity and total virus counts are essential for in-depth sample characterization.
Versatility - More than you can count
Our ComboDye™ reagent and ViroTag® reagents offer the optimal solution for all virus quantification needs.
The number of viruses and virus like particles (VLPs) quantifiable by the Virus Counter® platform are almost limitless.
With the Virus Counter® Platform, use our rapid, no wash procedure and take virus quantification to new levels of accuracy, speed and simplicity
Direct Antibody-Based Virus Quantification in Minutes
The ViroTag® detection system provides mission-critical data in real-time. This novel technology enables direct, biologically-specific quantification of viruses in minutes rather than the days or weeks required by more traditional and less accurate approaches.
With ViroTag® reagents, label your crude or purified samples, analyze on the Virus Counter® 3100, and gain an even higher level of quantitative precision. Enables immediate tracking of virus titer in your growth systems to:
- Optimize growth conditions
- Maximize yields
- Identify problems sooner
ViroTag® utilizes a fluorescently-labeled, high-affinity antibody which binds to a unique epitope specifically expressed by your virus of interest.

|INVX||for Influenza Virus|
|EV71||for Enterovirus 71|
for pseudo typed viruses such as Lentivirus or BacMam
|INVA||for Influenza A seasonal flu virus|
|INVB||for Influenza B seasonal flu virus|
- Detection of intact virus particles
- Simple & universal assay for enveloped viruses
- Fluorogenic dyes eliminate the need to wash
No Wash Assay
Both ComboDye and ViroTag labeling systems use a rapid, no wash-assay workflow.
The Virus Counter Platform Delivers More of What Matters When Quantitating Viruses
