鉴别胰岛素的种属来源具有重要的理论及实际意义。但是,不同种属胰岛素分子的一级结构近似,用常规方法很难准确地鉴别。本文的结果表明:(1)经典免疫法所获抗牛胰岛素血清由于含有牛胰岛素各种不同抗原决定簇的抗体,因而不能区分不同种属的胰
Identification of the source of insulin species has important theoretical and practical significance. However, the similarities in the primary structure of insulin molecules of different species are difficult to identify accurately by conventional methods. The results show that: (1) The anti-bovine insulin serum obtained by the classical immunization method can not distinguish between different species of pancreatic cancer due to the antibodies containing various antigenic determinants of bovine insulin
