Kh. Klotz et al., USE OF IRREVERSIBLE ELECTRICAL BREAKDOWN OF LIPID BILAYERS FOR THE STUDY OF INTERACTION OF MEMBRANES WITH SURFACE-ACTIVE MOLECULES, Biochimica et biophysica acta, 1147(1), 1993, pp. 161-164
Lipid bilayers were formed in the presence of different macromolecules
and high electrical fields were used to induce mechanical rupture of
the membranes. The kinetics of pore formation during irreversible brea
kdown was studied as a function of the macromolecules. We observed tha
t macromolecules having a strong binding affinity to the membrane alte
r the time course of pore formation significantly. We propose this met
hod as a simple test for adsorption of macromolecules to membranes.
