Description

Porcine dynorphin A (1-13) is a potent, endogenous κ opioid receptor agonist and is antinociceptive at physiological concentrations.

IC50 & Target

κ Opioid Receptor/KOR

 

In Vivo

Dynorphin A (1-13) exposure (33 μM) causes a significant loss in neuronal viability at 4 h with a visible destruction in neuronal morphology seen at 16 h. Exposure to dynorphin A (1-13) causes acute increases in [Ca2+]i in individual neurons similar to increases seen with acute NMDA treatment. Continuous exposure to dynorphin A (1-13) (100 μM) causes a significant loss of neurons over time[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.
