Product overview

Name BAM (8-22)
Biological description

BAM (8-22) is a product of the opioid precursor proenkephalin A. It is a potent activator of Mas-related GPCR (MRGPRs): MRGPRC C11 and hMRGPRX1.


BAM (8-22) does not contain the met-enekphalin motif (unlike BAM-22P) and therefore lacks affinity for opioid receptors.


Active in vivo. Produces itch and nociceptive sensations.
