Abstract
We describe a method of measuring neutron scattering of aligned membranes with the momentum transfer oriented parallel or partly perpendicular to the plane of the membranes. The method obtains the complete information for the structures within fluid membranes obtainable by scattering. Data from alamethicin- and magainin-induced pores are presented. Although the in-plane scattering curves of these two peptides are similar to each other, their off-plane scattering patterns are strikingly distinct. Magainin pores exhibit intermembrane correlations.
摘要
我们描述了一种测量取向膜的中子散射的方法，其动量转移方向平行或部分垂直于膜平面。该方法可获取通过散射得到的流体膜内结构的完整信息。给出了来自短杆菌肽A和蛙皮素诱导形成的孔的数据。尽管这两种肽的面内散射曲线彼此相似，但它们的面外散射模式却显著不同。蛙皮素孔表现出膜间相关性。
