ArachnoServer: a database of protein toxins from spiders.

11 Aug 2009 BACKGROUND: Venomous animals incapacitate their prey using complex venoms that can contain hundreds of unique protein toxins. The realisation that many of these toxins may have pharmaceutical and insecticidal potential due to their remarkable ... Read more...

Single molecule force measurements delineate salt, pH and surface effects on biopolymer adhesion.

29 Jun 2009 In this paper we probe the influence of surface properties, pH and salt on the adhesion of recombinant spider silk proteins onto solid substrates with single molecule force spectroscopy. A single engineered spider silk protein (monomeric C(16) or ... Read more...

Mass spectrometric characterisation and quantitation of selected low molecular mass compounds from the venom of Haplopelma lividum (Theraphosidae).

30 May 2009 Arachnid venoms present a diverse and complex matrix for investigation, with their latent potential for innovative drug and pesticide design largely unrealised. The characterisation and quantification of selected low molecular mass compounds ... Read more...

Technical information about 'Spiders'

Definition: Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (From Barnes, Invertebrate Zoology, 5th ed, p508; Smith, Insects and Other Arthropods of Medical Importance, 1973, pp424-430)
