WebThis chapter describes a simple method for overproducing a soluble form of the tobacco etch virus (TEV) protease in Escherichia coli and purifying it to homogeneity so that it may be used as a reagent for removing affinity tags from recombinant proteins by site-specific endoproteolysis. The protease is initially produced as a fusion to the C-terminus of E. coli … WebThe purified virus particles remain intact and are suitable for vector, vaccine, or structural studies and can also be used as seed stock for further rounds of infection. The hexon may be used to produce crystals suitable for high-resolution X-ray crystallographic studies. Briefly, virus is propagated in HeLa cell suspension cultures.
