摘要

我们首次报道了锌离子(Zn2+)通过将血红素铁从肌红蛋白(Mb)中“拖出”,显著增强了鲁米诺-过氧化氢(鲁米诺- h2o2)系统的化学发光(CL)信号。将其与肌红蛋白适配体(Mb适配体)特异性识别相结合,可以对牛肉样品中的Mb含量进行敏感和特异性的定量分析。

A highly sensitive flow injection chemiluminescence method for myoglobin detection in beef samples based on zinc ion-induced “dragging” of heme iron†

A highly sensitive flow injection chemiluminescence method for myoglobin detection in beef samples based on zinc ion-induced “dragging” of heme iron†

We report for the first time that zinc ions (Zn2+) significantly enhance the chemiluminescence (CL) signal of the luminol–hydrogen peroxide (luminol–H2O2) system by “dragging” heme iron out of myoglobin (Mb). Integrating this with myoglobin aptamer (Mb aptamer) specific recognition enables sensitive and specific quantification of Mb content in beef samples.
