Membrane scaffold proteins derive from apolipoprotein (apo; A-I). They are used in membrane protein sciences for the stabilization of membrane proteins in a lipid environment after the removal of the cell membrane. The size of the nanodisc is determined by the MSP that was used to create the disc. MSP1D1 dH5 creates nanodiscs of ∼7 to 8 nm in diameter.
