    Product Description

    Dynorphin B (1-9) is a neuropeptide and N-terminal cleavage product of dynorphin B, an endogenous opioid.1 Formation of dynorphin B (1-9) is blocked by N-ethylmaleimide (NEM), a non-selective inhibitor of cysteine peptidases. Dynorphin B (1-9) is a competitive inhibitor of dynorphin A (1-9), binding to the 60 kDa N-terminal fragment of puromycin-sensitive aminopeptidase (ApPS60).2

    WARNING This product is not for human or veterinary use.
