Fig.4. Changes in relative extinction of the 30kDa protein and a 70kDa protein (for comparison) upon treatment with 1µmoll-1 proctolin. Summary of 11 experiments. The relative changes in the extinctions of the 30kDa and the 70kDa band of proctolin-treated samples and untreated samples were compared in each experiment. The extinctions result from immunoreactivity of the anti-phosphoserine antibody. Values are means ± S.D., *P<0.05, Students t-test.
