Engineered disulfides improve mechanical properties of recombinant spider silk.

29 Apr 2009 Nature's high-performance polymer, spider silk, is composed of specific proteins, spidroins, which form solid fibers. So far, fibers made from recombinant spidroins have failed in replicating the extraordinary mechanical properties of the native ... Read more...

Silk fibroin solution properties related to assembly and structure.

8 Nov 2008 The impact of physiological factors on silk fibroin solution properties was studied. Specifically, the impact of fibroin concentration, protein purity, cation type and concentration, and pH on aqueous solution viscosity, shear behavior, and surface ... Read more...

Properties of synthetic spider silk fibers based on Argiope aurantia MaSp2.

4 May 2008 Spiders have evolved a complex system of silk producing glands. Each of the glands produces silk with strength and elasticity tailored to its biological purpose. Sequence analysis of the major ampullate silk reveals four highly conserved ... Read more...
