Coating a substrate with a monolayer of self-assembling proteins, comprises providing stabilized aqueous solutions with self-assembling proteins, and contacting a surface of the substrate with the stabilized protein-containing solution

摘要

The method comprises providing stabilized aqueous solutions with self-assembling proteins, where: the self-assembling protein is provided in an aqueous solution and then an aqueous solution containing a non-ionic surfactant is added in portions to the protein-containing solution from the self-assembling protein in the absence of substances that are suitable for the cleavage of disulfide bonds; and the final concentration of surfactant is calculated according to an equation as given in the specification, and contacting a surface of the substrate with the stabilized protein-containing solution. The method comprises providing stabilized aqueous solutions with self-assembling proteins, where: the self-assembling protein is provided in an aqueous solution and then an aqueous solution containing a non-ionic surfactant is added in portions to the protein-containing solution from the self-assembling protein in the absence of substances that are suitable for the cleavage of disulfide bonds; and the final concentration of surfactant is calculated according to an equation as given in the specification, contacting a surface of the substrate with the stabilized protein-containing solution thus producing a protein-containing coating on the substrate, and removing the supernatant solution from the coated substrate and/or drying the coated substrate. Independent claims are included for: (1) a method for stabilizing solutions with self-assembling proteins; and (2) a substrate with a protein-containing coating.
