摘要

DNA arranges into rectangular columnar superlattices between interdigitated lipid bilayers in the low-temperature gel phase of the lipoplexes of the cationic o-ethylphosphatidylcholines.The interlamellar correlation in the DNA ordering is not observed within the liquid crystalline lipid phase.The gel-liquid crystalline phase transition of the lipid induces a contraction of the DNA smectic array that matches the increased positive charge density of the membrane surface caused by the interdigitated-noninterdigitated transition.The transition proceeds via an intermediate state that has an expanded lamellar repeat period.
