ABSTRACT:
The invention features methods and apparatuses for spinning silk protein fibers (biofilaments) from recombinant biofilament proteins. The methods are particularly useful for spinning fibers of spider silk or silkworm silk proteins from recombinant mammalian cells and may be used to spin such fibers for use in the manufacture of industrial and commercial products.
