摘要: 蜘蛛丝是目前所知强度最高的天然蛋白质纤维,作为生物材料在工业、军事、医学等领域有很多用途,但是从自然界获得大量的蜘蛛丝是非常困难的。在本研究中,用piggyBac转基因载体将蜘蛛纵丝基因(MaSp1)导入家蚕染色体中,结果显示在稳定继代的第二代家蚕吐出的蚕茧中含有蜘蛛纵丝蛋白,获得了在蚕茧中稳定表达蜘蛛丝蛋白的转基因家蚕,该家蚕可以大量生产含有蜘蛛纵丝蛋白的复合茧丝新纤维。本研究表明利用转基因家蚕大量生产各种新型复合蛋白质纤维材料具有潜在的应用前景。

Abstract: Spider silk is an excellent fibre with combination of tensile strength and elasticity, but the isolation of large amount of spider silk in nature is difficult. Such superior biomaterials could be useful for industrial and medical purposes. In this study, We induce spider dragline silk (MaSp1) gene into the chromosome of silkworm by piggyBac transgenic vector. The result showed the trangeic silkworm can produce a new composite silk fiber that contains MaSp1 protein. It also suggested that produce many kinds of new composite protein fiber material by transgenic silkworm is feasible.

Key words: transgenic silkworm , spider silk , composite silk
