摘要: Transgenic silkworms stably expressing synthetic spider silk genes or composite silkworm/spider silk genes are disclosed. The exogenous spider silk genes are stably intergrated into a defined site of the fibroin heavy chain intron or a fibroin light chain intron of silkworms. Synthetic spider silk proteins and composite spider silk-silkworm genes and proteins are provided. The expression of exogenous spider silk genes is driven by the endogenous fibroin heavy chain promoter, improving the genetic stability of transgenic silkworms. The composite silkworm/spider silk fibers exhibit exceptional mechanical performance, compared to normal silkworm silk fibers and other transgenic silkworm fibers.

摘要: Methods for forming useful films using recombinant spider silk protein are discussed. In one embodiment, the method involves dissolving silk protein in a sufficient quantity to form a film suspended in a solvent. The solution is then mixed with a compound selected from water, acids, imidazole crosslinking agents, antibiotics, nanoparticles, surfactants and combinations thereof. Solubilisation of the protein in the solution is effected by microwave exposure. Once solubilized the microwave treated solution is poured onto a suitable substrate and dried in order to result in the final film, the protein may be plant, mammal or bacterially derived. The film has widespread use and can be combined with any one of a number of substrates, examples of which include: a cosmetic composition; a pharmaceutical or medical composition, drug delivery system, artificial cell, contact lens coating, sustained-release drug delivery system, artificial skin graft; food composition; automotive part; aeronautic component; computer or data storage device, building material, textile, filter material, membrane material, nanomaterial, electronic component and combinations thereof.

摘要: 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.
