Virus Counter® Reagents
Rapid, Direct, Biologically Relevant Virus Quantitation
The Virus Counter® platform, Combo Dye® and ViroTag® reagents, were specially developed to quantify viruses rapidly and with high specificity utilizing the Virus Counter® instrument. The reagents offer a biologically-relevant readout with versatility to address unique quantification needs. Virus samples stained with Combo Dye® or ViroTag® reagents are quantified after a 30 minute incubation. ComboDye® reagent is based on a dual stain approach that uses fluorogenic dyes to detect virus particles. The reagent can be used for quantification of all enveloped viruses. The ViroTag® reagent product line is based on an antibody-driven recognition of virus particles. Antibodies selected in the ViroTag® reagents are labeled with fluorophores and are highly specific for indicated viruses.
The ViroTag® detection system provides mission-critical data in real-time. This novel technology enables direct, biologically specific quantification of viruses. by utilizing a fluorescently-labeled, high-affinity antibody which binds to a unique epitope expressed by your virus of interest.
Use the ViroTag® reagents to label your virus samples and analyze on the Virus Counter® instrument.
Enables real-time tracking of virus titer in your process:
- Optimize growth conditions
- Maximize yields
- Identify problems sooner
ViroTag® Reagent Kits

The Virotag® DY detection system is a ready-to-use, simple, and universal approach for virus quantification. This reagent is compatible with all enveloped viruses, with single or double-stranded DNA or RNA genome. This universal reagent is based on a dual strain approach that identifies intact virus particles by simultaneous detection of protein and nucleic acid signal. The use of fluorogenic dyes eliminates the need to wash.
