Abstract
The present application provides fibers made from recombinant hagfish intermediate filament proteins. Methods of expressing and purifying the proteins, and methods of creating the fibers, are likewise disclosed. The method of purifying protein yields larger quantities of hagfish protein than have been previously achieved, and the fibers have the highest mechanical properties yet recorded for recombinant hagfish protein fibers.
