Virotag® Reagents
Rapid, Direct, Biologically Relevant Virus Quantitation
The Virus Counter® platform 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 Virotag® reagents are quantified after a 30-minute incubation.
Virotag® DY reagents are based on a dual stain approach that uses fluorogenic dyes to detect virus particles. The reagent can be used for the 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.
Virotag® AB and Virotag® DY Reagents
Use the Virotag® AB (antibody-based) and Virotag® DY (dye-based) 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

If your sample is compatible with the universal Virotag® DY reagent and an antibody-based Virotag® reagent, please consult a specialist about your specific needs to choose the optimal reagents for your sample.
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 that 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.
- High specificity due to antibody-based labeling system
- Enables detection of viruses and virus like particles
- Ready-to-use reagent with a simple no-wash protocol
