By applying of genetic engineering strategies a Bombyx mori silk fibroin-RGD fusion protein(Silk-RGD) was synthesize,which showed a high cell adhesive ability,and the technological conditions for salting-out purification of the Silk-RGD were studied.

From the state of frozen silk fibroin solution prepared by dissolving silk fibroin in ternary solvent CaCl2.

Graft modification of silk with vinylsiloxane monomer;
