摘要:
New and improved methods and systems for modeling the performance of selected company metrics. Multiple, non-traditional sets of objective data along with mathematical analytical techniques are used to provide transparency and visibility into company performance relating to the particular metrics. Company inflection points and changes in strategy may be identified. The performance of a company and/or the performance of a selected industry or industry sector may be analyzed.
摘要:
Methods and apparatuses for preparing protein fibers (biofilaments) from recombinant biofilament proteins are disclosed. The methods are particularly useful for spinning fibers of spider silk or silkworm silk proteins from recombinant sources and may be used to spin such fibers for use in the manufacture of industrial and commercial products.
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:
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:
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.

摘要:
A method of producing synthetic spider silk, including: transforming Escherichia coli with an expression vector; fermenting the transformed E. coli in a culture medium; inducing spider silk protein expression in the cultured E. coli; extracting the spider silk; and purifying the spider silk. Related vectors and genetically modified cells are also disclosed.
