Dynorphin B (1-9)

Dynorphin B (1-9) is the N-terminal fragment of dynorphin B, a neuropeptide whose production is blocked by the cysteine protease inhibitor N-ethylmaleimide (NEM) . This peptide is a valuable research tool for studying dynorphin processing, kappa-opioid receptor signaling, and neuropeptide biology in both in vitro enzymatic assays and in vivo models of pain and addiction.
