Mode of Action
Several methods have been used to determine the mechanisms of antimicrobial peptide activity. In particular, solid-state NMR studies have provided an atomic-level resolution explanation of membrane disruption by antimicrobial peptides.
| Methods | Applications |
|---|---|
| Microscopy | to visualize the effects of antimicrobial peptides on microbial cells. |
| Fluorescent dyes | to measure antimicrobial peptides to permeabilize membrane vesicles. |
| Ion channel formation | to assess the formation and stability of an antimicrobial-peptide-induced pore. |
| Circular dichroism and orientated circular dichroism | to measure the orientation and secondary structure of an antimicrobial peptide bound to a lipid bilayer |
| Dual Polarization Interferometry | to measure the different mechanisms of antimocrobial peptides |
| Solid-state NMR spectroscopy | to measure the secondary structure, orientation and penetration of antimicrobial peptides into lipid bilayers in the biologically relevant LIQUID-CRYSTALLINE STATE |
| Neutron and X-ray diffraction | to measure the diffraction patterns of peptide-induced pores within membranes in oriented multilayers or liquids |

Famous quotes containing the words mode of, mode and/or action:
“That the mere matter of a poem, for instance—its subject, its given incidents or situation; that the mere matter of a picture—the actual circumstances of an event, the actual topography of a landscape—should be nothing without the form, the spirit of the handling, that this form, this mode of handling, should become an end in itself, should penetrate every part of the matter;Mthis is what all art constantly strives after, and achieves in different degrees.”
—Walter Pater (1839–1894)
“The love of their country is with them only a mode of flattering its master; as soon as they think that master can no longer hear, they speak of everything with a frankness which is the more startling because those who listen to it become responsible.”
—Marquis De Custine (1790–1857)
“Let the will embrace the highest ideals freely and with infinite strength, but let action first take hold of what lies closest.”
—Franz Grillparzer (1791–1872)
