Fig. 4. Effect of He-LWamide II and Hydra-RFamide I on track length. Peptide concentration is plotted against the distance migrated during 1 h (track length). Values shown are means + S.E.M. Asterisks indicate results that are significantly different from the control values (shown in the far-left column in each panel) (t-test; ^*P<0.05, ^**0.01). Sample size was minimally 50.
