Figure 8. The effects of protein kinase inhibitors on the activation of ERK1/2 signaling in intact Drosophila.

ERK1/2 activation in Drosophila fed the inhibitors in their food were determined using Western blots probed with a phosphorylation site- or total protein-specific antibody. The labeling and symbols are as described in the legend to Figure 2. Panels A through C represent data from 3 different Western blots. See Figure S8 for representative Western blots.
