A radioiodinated phloretyl-.beta.-alanyl-secretin, its salts and its protected derivatives. A process for the manufacture of a radioiodinated phloretyl-.beta.-alanyl-secretin and/or a salt thereof which process involves reacting phloretyl-.beta.-alanyl-secretin and/or a salt thereof with radioactive iodine. Phloretyl-.alpha.-alanyl-secretin, its salts and its protected derivatives. A method for the determination of secretin in a sample, which involves; mixing the sample with a known amount of a radioiodinated phloretyl-.beta.-alanyl-secretin and an antibody specific for secretin; measuring the degree of binding of the labelled radioiodinated phloretyl-.beta.-alanyl-secretin; and determining the amount of secretin present in the sample by comparing the degree of binding with a standard curve which has been obtained by adding known amounts of secretin to a defined mixture of the radioiodinated phloretyl-.beta.-alanyl-secretin and the antibody and determining the degree of binding for this known amount of secretin.
一种放射性碘标记的芬乐酰基-β-丙氨酰-胰高糖素及其盐和保护衍生物。一种制造放射性碘标记的芬乐酰基-β-丙氨酰-胰高糖素和/或其盐的方法,该方法涉及将芬乐酰基-β-丙氨酰-胰高糖素和/或其盐与放射性碘反应。芬乐酰基-α-丙氨酰-胰高糖素及其盐和保护衍生物。一种测定样品中胰高糖素含量的方法,包括:将样品与已知量的放射性碘标记的芬乐酰基-β-丙氨酰-胰高糖素和特异性抗体混合;测量标记的放射性碘标记的芬乐酰基-β-丙氨酰-胰高糖素的结合程度;通过将结合程度与通过向定义的混合物中加入已知量的胰高糖素并测定该已知量胰高糖素的结合程度所获得的标准曲线进行比较,确定样品中胰高糖素的含量。
