Herein, we report a novel magnet-mediated antibody-boronate sandwich-typed assay (ABSTA) strategy for the ultrasensitive, specific, rapid, and enzyme-free detection of glycoproteins in complex samples. The proposed ABSTA method exhibited ultrahigh sensitivity for HCG with a detection limit of 0.19 mIU mL-1, which is approximately 40-fold lower than that of conventional sandwich enzyme immunoassay.
在此,我们报告了一种新颖的基于磁珠介导的抗体-硼酸酯三明治型测定(ABSTA)策略,用于在复杂样品中进行糖蛋白的超灵敏、特异、快速和无酶检测。所提出的 ABSTA 方法对 HCG 表现出超高的灵敏度,检测限为 0.19 mIU mL-1,大约比传统的夹心酶免疫测定低 40 倍。
