Rheological characterization of hydrogels formed by recombinantly produced spider silk
Many fibrous proteins such as spider silks exhibit impressive mechanical properties and are highly biocompatible leading to many potential biomaterial applications. For applications such as tissue engineering, polymer hydrogels have been proposed as an effective means of producing porous but stable scaffolds. Here, nanofiber-based hydrogels were produced from engineered and recombinantly produc...
متن کاملHigh-Toughness Silk Produced by a Transgenic Silkworm Expressing Spider (Araneus ventricosus) Dragline Silk Protein
Spider dragline silk is a natural fiber that has excellent tensile properties; however, it is difficult to produce artificially as a long, strong fiber. Here, the spider (Araneus ventricosus) dragline protein gene was cloned and a transgenic silkworm was generated, that expressed the fusion protein of the fibroin heavy chain and spider dragline protein in cocoon silk. The spider silk protein co...
متن کاملUbiquitous distribution of salts and proteins in spider glue enhances spider silk adhesion
Modern orb-weaving spiders use micron-sized glue droplets on their viscid silk to retain prey in webs. A combination of low molecular weight salts and proteins makes the glue viscoelastic and humidity responsive in a way not easily achieved by synthetic adhesives. Optically, the glue droplet shows a heterogeneous structure, but the spatial arrangement of its chemical components is poorly unders...
متن کاملSpider Silk
Some things about spider silk are difficult to understand.The genetic code for one of the more perplexing types of silk—the strands spiders use to weave their egg cases. Each case must be tough enough to keep out parasites, impermeable to rain and fungus, and breathable while insulating eggs from temperature extremes. These qualities alone would make an impressive fabric.The egg cases may even ...
متن کاملSpider silk fibers spun from soluble recombinant silk produced in mammalian cells.
Spider silks are protein-based "biopolymer" filaments or threads secreted by specialized epithelial cells as concentrated soluble precursors of highly repetitive primary sequences. Spider dragline silk is a flexible, lightweight fiber of extraordinary strength and toughness comparable to that of synthetic high-performance fibers. We sought to "biomimic" the process of spider silk production by ...
