Peptide15-MBP is specific for Kly18. A)

<p>The peptide15-MBP fusion protein interacted exclusively with Kly18, thereby demonstrating that peptide15 was specific for Kly18. <b>B)</b> To demonstrate that binding to Kly18 was mediated by peptide15 and not by MBP itself, control experiments were performed using MBP instead of MBP-peptide15. Error bars represent standard deviations between three experiments.
