Abstract
A fingerprint-like pattern across multilamellar, lipid-DNA complexes is attributed to DNA condensed as parallel helices between lipid bilayers. It is argued that the patterning indicates the existence of 3-D correlation forces between DNA-covered bilayers, following the DNA-driven formation of multilamellar liposomes from unilamellar vesicles.
摘要
多层脂质 - DNA 复合物上类似指纹的图案归因于在脂质双层之间以平行螺旋形式凝聚的 DNA。有人认为，这种图案表明在 DNA 驱动单层囊泡形成多层脂质体之后，被 DNA 覆盖的双层之间存在三维相关力。
