Received: 16 April 2010; in revised form: 12 May 2010 / Accepted: 13 May 2010 / Published: 20 May 2010 Abstract: Silk sericin (SS) can accelerate cell proliferation and attachment; however, SS can be extracted by various methods, which result in SS exhibiting different physical and biological properties. We found that SS produced from various extraction methods has different molecular weights, zeta potential, particle size and amino acid content. The MTT assay indicated th
