The nanodisc (ND) is a self-assembled discodial particle composed of phospolipids and two amphipathic belt proteins, termed Membrane Scaffold Proteins (MSP). This stable, monodispersed nanometer-sized particle (a diameter of 10 nm and a height of ~5 nm), each resembling a piece of a lipid bilayer, provides a native-like model of the cell membrane. A single membrane protein can be reconstituted into the nanodisc, which are a promising tool in studies of membrane proteins in their functional state. We have preliminary QCM data which shows we can assemble nanodisks onto grafted phosphocholine surfaces, and in principle, this could result is a nanodisc layer 'floating' on a cushion of water, analogous to floating lipid bilayers. This could potentially be a very useful system for studying membrane proteins. In this experiment, we wish to characterise the structure of these adsorbed layers.
