Deltorphin 2 is a selective peptide agonist for the δ opioid receptor.

IC50 & Target

δ opioid receptor[1]

In Vitro

Deltorphin 2 ([D-Ala2]-Deltorphin II) is enzymatically stable, amphibian heptapeptides that has a high affinity and selectivity for delta-opioid receptor. Deltorphin 2 is the most selective natural delta opioid receptor agonist[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
