WebTMV has a well-defined in vitro assembly system controlled by pH, ionic strength, and protein concentration. TMV particles can be produced in large quantities from infected tobacco plants (Young et al., 2008; Ma et al., 2012). TMV is both chemically and physically stable to solvents, pH (3.5–9.0), temperature (up to 90°C), and reducing agents.
