[Abstract]  Giant unilamellar vesicles (GUVs) are a widely used model system for a range of applications including membrane biophysics, drug delivery, and the study of actin dynamics. While several protocols have been developed for their generation in recent years, the use of these techniques involving charged lipid types and buffers of physiological ionic strength has not been widely adopted. This protocol describes the generation of large numbers of free-floating GUVs, even for charged lipid types and buffers of higher ionic strength, using a simple approach involving soft polyacrylamide (PAA) gels. This method entails glass cover slip functionalization with (3-Aminopropyl)trimethoxysilane (APTES) and glutaraldehyde to allow for covalent bonding of PAA onto the glass surface. After polymerization ... [摘要]  [摘要]巨型单层囊泡(GUV)是一种广泛使用的模型系统,其应用范围包括膜生物物理学,药物递送以及肌动蛋白动力学研究。虽然一些协议已经为他们这一代人在最近几年已开发,利用这些T的echniques涉及带电脂质的类型和生理离子强度缓冲液一直没有得到广泛的广告Ø PTED。Thi的方案描述了使用包括聚丙烯酰胺(PAA)凝胶的简单方法,即使对于带电荷的脂质类型和更高离子强度的缓冲液,也产生了大量的自由浮动GUV。此方法需要使用(3-氨基丙基)三甲氧基硅烷(APTES)和戊二醛对玻璃盖玻片进行功能化,以允许将PAA共价键合到玻璃表面上。PAA聚合后,将凝胶真空干燥。随后,将选择的脂质均匀地分散在干燥的凝胶表面上,并且可以使用具有不同离子强度的缓冲液来重新水化凝胶并形成GUV。该协议对于在生理条件下生产大量由不同脂质组成的自由浮动GUV而言是可靠的。它可以方便地用常用的实验室试剂进行。
