Bachem – Your Partner for Peptide Toxins

Peptide and protein toxins are widespread in the animal kingdom as well as in microorganisms and fungi.Their unique properties make them valuable tools in various areas of research. The conotoxins produced by marine snails can target receptors on sodium or calcium channels depending on their structure. ω-conotoxin MVIIA is a most efficient analgetic. Sea anemone toxins can have high affinity for sodium channels of heart muscle neuromuscular junctions or for potassium channels of several cell types.

Scorpion toxins also act on sodium or potassium channels, whereas many spider toxins block calcium channels. Besides toxins from these invertebrates, Bachem offers peptide toxins from venomous snakes, insects and further species. Analogues and labelled peptides are also available. Most of our products have been obtained by chemical synthesis. Bachem offers:
