Daily and seasonal changes in the stickiness of viscous capture threads in Argiope aurantia and Argiope trifasciata orb-webs.

27 Feb 2009 The spirally arrayed viscous capture threads of spider orb-webs are formed of small, regularly spaced adhesive droplets and are responsible for retaining insects that strike the web, giving a spider more time to subdue these prey. These sticky ... Read more...

Synthesis of silk fibroin-insulin bioconjugates and their characterization and activities in vivo.

30 Oct 2006 The regenerated liquid silk fibroin with an average molecular mass of about 60 kDa consists of 18 kinds of amino acids containing approximately 10% of polar amino acids with hydroxyl and amino groups such as serine and lysine. The liquid silk ... Read more...

Molecular mechanisms of spider silk.

30 Aug 2006 Spiders spin high-performance silks through the expression and assembly of tissue-restricted fibroin proteins. Spider silks are composite protein biopolymers that have complex microstructures. Retrieval of cDNAs and genomic DNAs encoding silk ... Read more...
