Abstract:
The invention provides a protein composition derived from silk fibroin, which composition possesses enhanced solubility and stability in aqueous solutions. The primary amino acid sequence of native fibroin is modified in the SDP such that cysteine disulfide bonds between the fibroin heavy and fibroin light protein chains are reduced or eliminated. Additionally, the composition can have a serine content that is reduced by greater than 40% compared to native fibroin protein, and the average molecular weight of the SDP is less than about 100 kDa.

Claim (Index 14):
The protein composition of  claim 1  wherein the protein composition maintains an optical absorbance in aqueous solution of less than 0.25 at 550 nm after at least five seconds of ultrasonication.
