Cat. No. 3139
Alternative Name: Vapreotide
Biological ActivityCyclic octapeptide somatostatin analog (Ki values are 0.7, 5.4, 30.9, 45 and > 1000 nM for sst5, sst2, sst3, sst4 and sst1 receptors respectively). More metabolically stable than somatostatin (Cat. No. 1157). Inhibits growth hormone release in vivo.
(Modifications: Phe-1 = D-Phe, Trp-4 = D-Trp, Trp-8 = C-terminal amide, Disulfide bridge between 2 - 7)
