荧光极化(FP)已成为定量分析小可溶性荧光标记探针与较大可溶性蛋白结合及其被其他分子取代的有力技术。在这里,我们描述了一个详细的方案,以识别能够靶向p53- mdm2 / MDMX相互作用的小分子,使用罗丹明标记的p53肽的荧光偏振测定。
Fluorescence polarization (FP) has become a powerful technique to quantitatively analyze the binding of a small soluble fluorescence-labeled probe to a larger soluble protein and its displacement by other molecules. Here, we describe a detailed protocol to identify small molecules capable of targeting p53-MDM2/ MDMX interactions using a fluorescence polarization assay with Rhodamine-labeled p53 peptides.
