A 28-residue peptide corresponding to the entire amino acid sequence of vasoactive intestinal polypeptide of guinea pig origin (gVIP) was synthesized by assembling 6 peptide fragments, followed by thioanisole-mediated deprotection with 1 M trimethylsilyl trifluoromethanesulfonate in trifluoroacetic acid. The synthetic peptide was biologically as active as synthetic porcine VIP, but behaved immunologically in a different manner from the above mammalian VIP.
