Figure 1. Accumulation of recombinant 2G12-KDEL and 89.6P gp140ΔCFI-KDEL env in leaves using the Nb/p19 transient plant expression system.

Extracts produced from the equivalent of 3 mg (2G12-KDEL) (A) and 4.5 mg 89.6Pgp140ΔCFI env (B) of leaf biomass harvested from days 6–24 post-infiltration were loaded onto the gel and proteins detected by anti-KDEL Western blotting.
