摘要:
Purified secretin is obtained by subjecting crude secretin to reversed-phase high-performance liquid chromatography using, as an eluant, a solvent mixture of an acid or salt thereof and an organic solvent.
摘要:
A heptacosapeptide is disclosed having the following structural formula: Boc-His(Boc)-Ser(Bu t )-Asp(OBu t )-Gly-Thr(Bu t )-Phe-Thr(Bu t )-Ser(Bu t )-Glu(OBu t )-Leu-Ser(Bu t )-Arg(X)-Leu-Arg(X)-AsplOBu t )-Ser(Bu 2 1-Ala-Arg(X)-Leu-Gln-Arg(X)-Leu-Leu-Gln-Gly-Leu-Val-NH2, in which X is a group having the formula: where R is an alkyl or alkoxy and m is an integer of 1 to 3, provided that R's may be the same or different in case m is 2 or 3. Said heptacosapeptide can be produced by condensation of a novel decapeptide with a heptapeptide which are also disclosed. The heptacosapeptide can be used for production of a secretin.
