AnaSpec Introduces Custom Services & Reagents for Hydrocarbon-Stapled Peptides


AnaSpec now offers custom synthesis of hydrocarbon-stapled peptides.

Fremont, CA, September 20, 2009 --(PR.com)-- The innovative technique of hydrocarbon stapling in peptides is introducing valuable new functionality to peptide-related research. AnaSpec now offers custom synthesis of hydrocarbon-stapled peptides.

Hydrocarbon-stapled peptides are peptides capable of forming stable alpha helical structure as a result of “hydrocarbon stapling.”1,2 Many biological pathways, such as signal transduction, occur because of intracellular protein-protein interactions, which frequently are mediated by the a-helix structures of proteins. However, the use of short protein fragments (peptides) leads to a loss of secondary structure, which makes them susceptible to proteolysis and impermeable across cell membrane.1 Verdine’s group has shown that these problems could be overcome by a chemical modification of an alpha-helical peptide they termed hydrocarbon-stapled peptide.1,2 The modified hydrocarbon-stapled peptide is helical, relatively protease resistant, cell-permeable and binds with increased binding affinity to its target. Hydrocarbon stapling may provide a useful strategy in researching experimental and therapeutic modulation of protein-protein interactions as well as in in vivo pharmacokinetics studies.

In addition to offering stapled peptides [(i and i+4) and (i and i+7)] custom synthesis service, AnaSpec offers Fmoc amino acids for use in synthesizing stapled peptides; as well as three GO™ (catalog) stapled peptides.
