Giant vesicles (GVs) are widely-used model systems for biological membranes. The formulation of these vesicles, however, can be problematic and artifacts, such as degraded molecules or left-over oil, may be present in the final liposomes. The rapid formulation of a high number of artifact-free vesicles of uniform size using standard laboratory equipment is, therefore, highly desirable. Here, the gentle hydration method of glass bead-supported thin lipid films has been enhanced by adding a vortexing step. This led to the formulation of a uniform population of giant vesicles. Batches of glass beads coated with different lipids can be combined to produce vesicles of hybrid lipid compositions. This method represents a stable approach to rapidly generate giant vesicles.
巨型囊泡(GVs)是用于生物膜的广泛使用的模型系统。然而,这些囊泡的制备可能存在问题,并且最终的脂质体中可能存在诸如降解分子或残留油等假象。因此,非常希望使用标准实验室设备快速制备大量无假象、大小均匀的囊泡。在这里,通过添加涡旋步骤改进了玻璃珠支撑的薄脂质膜的温和水合方法。这导致了均匀的巨型囊泡群体的形成。可以将涂覆有不同脂质的玻璃珠批次组合起来,以产生具有混合脂质组成的囊泡。该方法代表了一种快速生成巨型囊泡的稳定方法。
