Abstract
Networks, hydrogels, and methods for networks and hydrogels comprising proteinaceous material consisting essentially of water soluble proteins and covalent interprotein crosslinks other than disulfide crosslinks.
Claims5
A composition comprising water soluble keratin proteins of about 40-60 kDa molecular weight, wherein the keratin proteins are substantially free of ultra-protein or inter-protein cystine disulfide bonds, wherein the composition forms a hydrogel when placed in an aqueous ion containing solution, and further wherein the keratin proteins are isolated under reductive conditions and are substantially free of oxidized cystines.
A composition comprising water soluble keratin proteins of about 40-60 kDa molecular weight, wherein the keratin proteins are substantially free of intra-protein or inter-protein cystine disulfide bonds, and wherein at least a portion of the cysteine side chains comprises a disulfide bond, wherein the composition forms a hydrogel when placed in aqueous solution containing monovalent ions.
