This fibroin silk SOLUTIONon ismade of 100%fibroin proteinthat is derived from the domesticated Bombyx mori silkworm. The product is manufactured in a manner to minimize contamination and has a low bioburden but is not considered sterile.fibroin protein is the major structural component of the silkwormrsquos cocoon fiber. fibroin offers great potential for use in medically related applications due to the high degree of biocompatibility and lack of immune response when implanted within the body. The silk fiber is solubilized into an aqueous fibroin SOLUTIONon which can then be used as an additive in culture or for producing 3D scaffolds for tissue-engineering related studies.As with traditional tissue-engineering approaches the silk scaffolds are typically seeded in vitro with a specific cell type as most cells will adhere to fibroin protein and then cultured over time to mimic tissue architecture. It has been shown that the silk fibroin protein can be degraded a number ofnaturally o
