Virus Counter® Plus Platform
Virus samples are labeled with specific reagents using a direct staining method or high-affinity monoclonal antibodies. The samples then undergo intense laser illumination, enabling rapid, direct, and precise quantification of the total viral particles within the sample.
Thanks to various detection methods, the Virus Counter® platform offers customized solutions tailored to individual quantification needs.
Key features:
- rapid and precise quantification - real-time quantification optimizes workflow processes
- automated sample processing - increases operational efficiency
- high sensitivity and precision - advanced detection ensures reliable results
- robust and user-friendly design - simplifies the use of the platform
Virus analytical reagents
The Virus Counter® Plus utilizes Virotag® reagents that can quantify Baculoviruses, Influenza A and B, Lentiviruses, and all enveloped viruses.
Virotag® AB
- the antibody-based detection
- enabling highly specific detection and quantification of viruses or virus-like particles in real-time
- fluorescently labeled high-affinity antibodies bind to a unique epitope of the virus
- ready-to-use reagent for a simple no-wash protocol
Virotag® DY
- the universal reagent identifies intact virus particles by simultaneously detecting proteins and nucleic acids
- nucleic acids and protein fluorogenic dye make a universal staining solution for enveloped viruses with single-stranded or double-stranded DNA or RNA genomes
- ready-to-use reagent for a simple no-wash protocol

The number of intact virus particles is quantified by detecting specific proteins and nucleic acids through fluorescence. The samples are stained with different dyes for each component and analyzed.
The limit of detection is 5×10^5 vp/mL.
The Virus Counter® Plus can process samples in an automated 96-well format.
The sample volume is 244 µL Virus + 6 µL dye.
The instrument has a dynamic range of 5×10^5 vp/mL to 1×10^9 vp/mL and the optimal range would be 1x10^7 vp/mL to 5x10^7 vp/mL.
The CV is typically below 10%.
No, the instrument is self-contained and requires no external source of gas or air for operation.
