Press Release Summary: AnaSpec has introduced its selection of channel blocker
peptides.

Press Release Body: San Jose, CA - February 18, 2008

AnaSpec, one of the world's largest providers of catalog peptides, has introduced
its selection of channel blocker peptides.

Peptide toxins are potent and selective compounds that can act on ion channels in
plasma membrane of excitable cells.1 These high specificity and affinity compounds,
often with diverse and selective pharmacologies, are used as pharmacological probes
to study and characterize various receptor proteins involved in ion-channel
function.1 These toxin peptides generally consist of a relatively small number of
structural frameworks that are particularly suited to addressing the crucial issues
of potency and stability.1 Multiple disulfide bonds constitute essential structural
elements in many of these bioactive peptides, which are generated by proteolytic
processing of prefolded protein precursors and then released from the cells in the
bioactive form into the extracellular medium to exert their physiological function.
