M65 TFA is a deleted peptide of maxadilan (61 a.a.) with deletion of the residues between positions 24 and 42 and is a specific antagonist of PACAP type 1 receptor that inhibits ANP secretion and can be used for relevant researches.
M65 (1 µM) completely blocks the cAMP accumulation stimulated by 100 nM of VIP, and partially inhibits the cAMP accumulation stimulated by 1 nM of maxadilan in rat cortical neurons[2].
