Dynorphin (2-17), amide, porcine

Dynorphins are opioid peptides derived from the precursor prodynorphin via cleavage by proprotein convertase 2 (PC2), yielding dynorphin A, dynorphin B, and α/β-neo-endorphin. These peptides are utilized in research on pain signaling, addiction, and neurological disorders, with applications in both in vitro receptor binding assays and in vivo behavioral studies.
