Figure 4.
Gel and Western blotting analysis of purified χE559P. Purified, plant-derived chimeric E559 (χE559P) was analyzed by Coomassie staining of polyacrylamide gels under nonreducing (panel A) and reducing (panel B) conditions, and by Western blotting under nonreducing (panels C and E) and reducing (panels D and F) conditions. For Western blotting, the nitrocellulose membranes were probed with HRP-conjugated antibodies specific for heavy chains (panels C and D), or with HRP-conjugated antibodies specific for light chains (panels E and F). The χE559P samples (lane 1) were probed with human-specific reagents, whereas E559Hyb samples (lane 2) were probed with murine-specific reagents. Abbreviations: HRP, horseradish peroxidase; M, molecular weight standards. Asterisks indicate the positions of the fully assembled antibodies.
