Endothelin Related Peptide | The synthetic peptide Sarafotoxin B (S6b, SRTX-B) manufactured by Peptide Institute Inc. was initially isolated from Snake, Atractaspis engaddensis and shows a very close structural and functional relationship to Endothelin-2 , which can be ordered as well from PeptaNova. The vasoconstictive effects induced by Sarafotoxin S6b seems to be weaker and not as long lasting.

The biological activity of Sarafotoxin S6b is examined by the Division of Pharmacology, Peptide Institute, Inc.
