ViroCheck NanoParticle Reference Kit

The ViroCheck NanoParticle Reference Kit is used for calibration of an intensity unit of fluorescence for flow cytometry analysis and concentration analysis for virus and extracellular vesicles. Through the application of the NIST-assigned intensity standards for a given fluorophore, instrument sensitivity and accuracy can be determined, permitting data comparison between flow cytometry instruments. In combination with a biological standard, these particles can also be used to quantify the level of biomarker expression.

ViroCheck NanoParticle Reference Kit features include:
• NIST-assigned ERF values to 15 commonly used flow cytometry filter set channels
• Enables normalization of fluorescence intensity scale for instrument accuracy and sensitivity
• NIST-verified nanoparticle concentration for counting of sub-micron biological samples such as viruses and extracellular vesicles
• Facilitates instrument to instrument data comparison
