A process for preparing a gut glucagon antigen composed of a peptide-carrier complex is disclosed, which comprises using as hapten a peptide represented by the following general formula; R-Lys-Arg-Asn-Lys-Asn-Asn-Ile-Ala-OH wherein R represents a hydrogen atom, an amino acid group or a peptide group containing 2 to 20 amino acid groups, and reacting it with a carrier in the presence of a binding agent for binding the hapten and the carrier to each other. Also, a process for preparing a gut glucagon antibody, which comprises administering the antigen described to mammals, and collecting the thus-produced antibody, is disclosed.
本发明揭示了一种制备肠饥饿素抗原的方法,该抗原由肽载体复合物组成,其中包括使用以下一般式表示的肽作为半抗原:R-Lys-Arg-Asn-Lys-Asn-Asn-Ile-Ala-OH,其中R代表氢原子、
氨基酸基团或包含2至20个
氨基酸基团的肽基团,并在绑定剂的存在下将其与载体反应以将半抗原和载体彼此结合。此外,本发明还揭示了一种制备肠饥饿素
抗体的方法,该方法包括将所述抗原注射给哺乳动物,并收集因此产生的
抗体。
