Panel A (top) – results using h2E2 mAb, Panel B (bottom) –
results using human IgG1 polyclonal antibody. A 1.5 mm thick,
7% acrylamide gel was loaded with 2 μg (10 μL) of
antibody per well, electrophoresed until the tracking dye reached the bottom of
the gel, and stained with Coomassie blue. Only the top portion of the gels are
shown – no bands were detected in the lower section of the gels. Panels
A and B depict photographs of single gels. Pre-electrophoretic incubation in
sample buffers under the indicated conditions was done for 10 minutes at either
22°C or 37°C, as indicated in the figure.
