Native electrospray mass spectrometry is a powerful method for determining the native stoichiometry of many polydisperse multi-subunit biological complexes, including multi-subunit protein complexes and lipid-bound transmembrane proteins. However, when polydispersity results from incorporation of multiple copies of two or more

Mesoporous Materials Synthesis

Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.
