A casein assay has been developed with aggregation induced emission character of BSPOTPE, which is a derivative of tetraphenylethene (TPE). The method exhibits a wide dynamic range of detection for casein from 10 μg ml(-1) to 5000 μg ml(-1), and a good linear range from 20 μg ml(-1) to 1250 μg ml(-1). With sample-pretreatment procedures, we can detect the casein in skimmed and full milk powder, avoiding the interferences from other components and illegal additives in milk.
已经开发出一种基于 BSPOTPE(四苯乙烯的衍生物)聚集诱导发射特性的酪蛋白检测方法。该方法对酪蛋白的检测范围很宽,从 10μg/ml 到 5000μg/ml,线性范围也很好,从 20μg/ml 到 1250μg/ml。通过样品预处理程序,我们可以检测脱脂奶粉和全脂奶粉中的酪蛋白,避免了牛奶中其他成分和非法添加剂的干扰。
