Protein interactions with ordered lipid films: Specific and unspecific binding

Communication: Membrane‐bound receptors improtant in biochemistry and medicine can be modeled using mono‐ and multilayer amphiphilic LB films. Proteins bound to the films (see figure) can possess either enzymatic activity or a specific binding capability that can be used in biological tests. Here, the interactions between polypeptides such as cytochrome C, insulin, and concanavalin A, and several types of films are evaluated.
