abstract：:Keratins are a family of structural proteins that can be isolated from a variety of tissues. "Soft" keratins are cytoskeletal elements found in epithelial tissues while protective tissues such as nails, hooves, and hair are composed of "hard" keratins. Hard keratins have been the subject of biomaterials investigations...
