The silk fiber of cocoons of silkworms of both the families consists of two major proteins, fibroin and sericin. The fibrion forms central core and sericin forms envelop. Fibroin and sericin, of mulberry silkworm, Bombyx mori deserve appreciable physioc-chemical properties and therefore, they are now recognized as excellent biomaterials in the field of tissue engineering, biotechnology and therapy. Sericin contributes about 20-30 per cent of total cocoon weight. It is characterized by its high content of serine and 18 amino acids, including essential amino acids. | Sericin from the cocoons of silkworm Antheraea mylitta L and Bombyx mori L for the reduction in hydrogen peroxide induced oxidative stress in feline fibroblasts
