A silk from the Mediterranean Pinna(Pinna sp.) has been utilized as a "Western Silk" like legendary cloth before Silk Road was established. But, marine local pinna(Artina pectinata) silk fiber has hardly investigated as a commercial fiber source after Silk Road was established, nor marine local pinna silk fiber has explored as a source for bioengineering. Bio-mimetics of marine local pinna silk fiber has a potential to inspire new insights to design novel fiber materials. We found a 3,4- Dihydroxyphenylalanine (Dopa) containing proteins from marine local pinna foot by Acid-Urea Poly Acrylamide Gel Electrophoresis(AUPAGE) with 4-Nitro Blue Tetrazolium chloride(NBT) staining and Arnow assay. We evaluated tensile strength of Pinna's silk, pulled the silk as 1mm/min by 10N Load cell. And that checked strain, stress, toughness of silk, afterward compared the mechanical properties of the Pinna's silk with several existing natural fibers. Marine local pinna silk fiber may offer wide application for fiber industry including medical sealant, ECM material for tissue/medical engineering, bio-plastic, and cosmetic additve.
