  • Publication number: 20170189557
    Abstract: There is provided a method of preparing a fluorescent silk fibroin solution, which includes a) obtaining scoured fluorescent silk fibroin by adding transgenic fluorescent silkworm cocoons to an aqueous solution including a scouring agent, heating the transgenic fluorescent silkworm cocoons at 40 to 60° C. for 8 to 24 hours and washing the transgenic fluorescent silkworm cocoons with distilled water, b) dissolving the scoured fluorescent silk fibroin at 40 to 60° C. for 1 to 5 hours in a solvent in which 15 mg to 1.5 g of dithiothreitol (DTT) is mixed per 100 mL of 9 to 9.6 M LiBr, and c) dialyzing the dissolved fluorescent silk fibroin in single distilled water for 48 to 96 hours. The scouring agent includes an alcalase and sodium hydrogen carbonate (NaHCO3). The conventional methods of preparing a silk fibroin solution from fluorescent silkworm cocoons have drawbacks in that silk fibroin is not dissolved at a low temperature and fluorescence is lost.
