to conduct highly complicated separations of both the labeled protein and the labeled peptides derived from it. Here, we propose a novel and universal methodology--Photo-Affinity Labeling on Magnetic microspheres (PALMm) designed to simplify and shorten the PAL protocol. In this context, we describe the preparation of PALMm reagents and the evaluation of their biochemical relevance regarding two ATP-binding
光亲和标记(PAL)是一种广泛用于识别蛋白质内结合位点的技术。尽管经典方法既通用又功能强大,但是它具有许多缺点,例如需要放射性标记PAL配体,以及需要对标记的蛋白质和衍生自其的标记的肽进行高度复杂的分离。在这里,我们提出了一种新颖而通用的方法-磁性微球上的光亲和标记(PALMm),旨在简化和缩短PAL协议。在这种情况下,我们描述了PALMm试剂的制备及其对两种ATP结合酶(己糖激酶和腺苷三磷酸酶)的生化相关性的评估。
