Description
PE 22-28 is a synthetic neuropeptide analog structurally related to spinorphin, an endogenous peptide fragment of hemoglobin’s beta chain, studied for its activity at opioid receptor pathways.
In laboratory research, PE 22-28 is examined for its selective antagonism at delta-opioid receptors while showing reduced activity at other opioid receptor subtypes, making it a useful tool for researchers isolating delta-receptor-specific signaling.
Researchers studying PE 22-28 focus on its use as a pharmacological probe for dissecting the roles of individual opioid receptor subtypes within complex neurochemical signaling networks.
Its structural derivation from spinorphin also links PE 22-28 to broader research into endogenous opioid peptide fragments and their regulatory functions.
PE 22-28 is supplied strictly for laboratory research into opioid receptor pharmacology and neuropeptide signaling.
