A cooperative effort between researchers at Mount Sinai School of Medicine in New York and the University of Illinois at Urbana-Champaign demonstrates a novel experimental system for single-molecule sensitivity FISH analysis of individual virus particles.
Entitled “One influenza virus particle packages eight unique RNAs as shown by FISH analysis”, the paper describes the methods by which the investigators demonstrated that Influenza A viruses each package eight unique viral RNA segments, and provides a powerful tool to understand the stoichiometry & composition of segmented viral RNAs inside virus particles. One of the techniques used for the quantitation of the particles measures step-wise photobleaching characteristics of the fluorescent labels to determine copy numbers of RNA segments within a viral particle.
For our Stellaris FISH technology users, this article describes a very useful tool for:
