The process of membrane fission is fundamental to diverse cellular processes such as nutrient uptake, synaptic transmission and organelle biogenesis, and it involves the localized application of curvature stress to a tubular membrane intermediate, forcing it to undergo scission. Alternative techniques for creating such substrates necessitate the use of micromanipulators or sophisticated optical traps and require a high level of technical expertise. We present a facile method to generate an array of membrane tubes supported on a passivated glass coverslip, which we refer to as supported membrane tubes (SMrTs). SMrT templates are formed upon hydration of a dry lipid mix in physiological buffer and subsequent flow-induced extrusion of the lipid reservoir into long membrane tubes with variable dimensions. Following surface passivation of coverslips, these templates can be formed from a variety of lipids, with as little as 1-2 nmol of lipid in a matter of 2 h, and can be used in membrane-curvature-sensitive fission assays.
