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, such as vaccine manufacturing, protein expression, antiviral development and other settings where viruses play a significant role.

Applications:

  • 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. Marketed under the tradename ViroTag®, this product category utilizes a fluorescently-labeled, high-affinity antibody targeted to the virus of interest. During a 1-minute sample analysis, the preparation is evaluated with the Virus Counter® 3100, an instrument developed expressly for the purpose of real-time virus quantification. The growing list of products includes kits to detect Adenovirus, Adeno-Associated Virus, Baculovirus and Influenza.

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

With our reagents ComboDye® and ViroTag® the number of viruses and virus-like particles quantifiable by the Virus Counter® is limitless.

ViroTag®

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 for Influenza, 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.

With the Virus Counter 3100, use this rapid, no-wash labeling procedure and take Influenza virus quantification to new levels of accuracy, speed and simplicity!
