Amperometric immunoassay for the obesity biomarker amylin using a screen printed carbon electrode functionalized with an electropolymerized carboxylated polypyrrole.

Amylin（islet amyloid polypeptide，AMY）是与肥胖、饥饿和饱腹感相关的激素，由胰岛β细胞与胰岛素共同分泌。本文报道一种用于检测AMY的安培免疫传感器。以丝网印刷碳电极（SPCE）为基底，电聚合聚丙烯酸吡咯（pPPA）形成富含羧基的导电聚合物修饰层，利用Mix&Go™聚合物活化羧基并共价固定抗AMY抗体...
