What Is PE-22-28?

PE-22-28 is a seven-amino-acid spadin analog investigated in preclinical models of TREK-1 channel inhibition, hippocampal neurogenesis and synaptic signaling. Intranasal delivery is frequently used in CNS-focused peptide research, which makes the pre-mixed spray a convenient laboratory format. Bulk lyophilized kits are available as PE-22-28 10-vial wholesale kits.
