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. equation image
