SPAI-1 is described as a polypeptide built of 49 aminoacid residues including four dedicated disuldide bridges. Originally isolated from porcine duodenum, SPAI-1 is now available from PeptaNova as synthetic peptide of highest purity. It is characterized as an inhibitor for Na+,K(+)-ATPase and alpha-amylase.
