Reference Nichols JW, Deamer DW. Net proton-hydroxyl permeability of large unilamellar liposomes measured by an acid-base titration technique. Proc Natl Acad Sci U S A. 1980 Apr77(4):2038-42. p.2041 right column 2nd paragraphPubMed ID6246519
Method The 9-aminoacridine technique involves measuring the rate of change in the vesicle internal pH as a large pH gradient (approximately 3 pH units) decays to equilibrium.
Comments For liposomes prepared from 98% phosphatidylcholine and 2% phosphatidic acid.
