Purification and characterization of biologically active peptides from spider venoms.

Abstract

Spider venoms represent invaluable sources of biologically active compounds suitable for use in life science research and also having a significant potential for biotechnology and therapeutic applications. The methods reported herewith are based on our long experience of spider venom fractionation and peptides purification. We routinely screen new peptides for antimicrobial and insecticidal activities and our detailed protocols are also reported here. So far these have been tested on species of Central Asian and European spiders from the families Agelenidae, Eresidae, Gnaphosidae, Lycosidae, Miturgidae, Oxyopidae, Philodromidae, Pisauridae, Segestriidae, Theridiidae, Thomisidae, and Zodariidae. The reported protocols should be easily adaptable for use with other arthropod species.
