摘要:
The present invention aims at providing a peptide fragment capable of improving biostability of a bioactive substance while maintaining the activity of the bioactive substance, and a bioactive substance to which the peptide fragment is added. The present invention relates to a partial peptide of a GA module having 5 to 25 amino acids, including a partial sequence of a GA module (SEQ ID NO: 1) and the amino acid sequence Ile-Asp-Glu-Ile-Leu (SEQ ID NO: 2), and a bioactive complex in which the partial peptide of the GA module is bound to a bioactive substance. The bioactive substance includes GLP-1, GLP-2, GIP, VIP, somatostatin, amylin, ghrelin, derivatives thereof, and the like.

摘要:
In a method for detecting a glucagon-secretin family peptide in a sample, the sample is contacted with a cleaving agent capable of digesting the glucagon-secretin family peptide by cleaving a peptide bond of at least one aspartic acid within the glucagon-secretin family peptide and thereby generating a plurality of peptide fragments, at least one of the peptide fragments containing an N-terminal end of the glucagon-secretin family peptide. The peptide fragment that contains the N-terminal end of the glucagon-secretin family peptide is then detected using liquid chromatography and mass spectrometry. The amount of peptide fragment that contains the N-terminal end of the glucagon-secretin family peptide in the sample can then be quantitated using a calibration curve.
