Taking advantage of the ability for in vitro assembly of the plant-infecting virus tobacco mosaic virus (TMV), rod-shaped nanoscale scaffolds presenting different addressable groups can be obtained. We have established procedures resulting in virus-like particles with randomly distributed functional groups, with different groups arranged in striped but randomized structures, and even with distinct groups clustered in adjacent, better-defined domains. The TMV coat protein (CP) variants combined in these approaches can either originate all from TMV mutants propagated in planta, or be mixed with CP expressed in E. coli (CPEc). Protocols for expression and purification of a CPEc-His6 mutant in E. coli as well as the different methods for in vitro assembly and the visualization by decoration of one CP type are explained in detail.
