ligand–4-azidophthalimide (AzPI) conjugate. As a proof of concept, we show that two different ligand–AzPI conjugates enabled highly specific fluorescence labeling of their individual target proteins even in crude cell lysates. This method was also applied to label endogenous target proteins inside living cells.
我们在这里提出一种使用配体4-叠氮基邻苯二甲酰亚胺(AzPI)共轭物的简单亲和标记方法。作为概念的证明,我们证明了两种不同的配体-AzPI偶联物即使在粗细胞裂解物中也能对其各自的靶蛋白进行高度特异性的荧光标记。该方法还应用于标记活细胞内的内源性靶蛋白。
