Membrane based Protein Complexes
The question arose whether the preparation technique is gentle enough to allow for protein complex assembly. To test this experimentally listeriolysin O was sprayed onto a bi-layer membrane. Listeriolysin O is a soluble protein that assembles on membranes in a non-covalent 30mer that inserts into the membrane and forms a large pore.
