F-肌动蛋白结合常数传统上通过与肌动蛋白微丝的离心共沉降来确定,其中结合的蛋白质用SDS-PAGE从肌动蛋白中分离并使用光密度法定量。在这里,我们证明,UV定量的反相HPLC分离的蛋白质提供了更高的准确性和灵敏度,可以完全自动化,并允许一个类似大小的蛋白质进行F-肌动蛋白竞争测定。
F-actin binding constants are traditionally determined by centrifugal cosedimentation with actin microfilaments, where bound protein is separated from actin with SDS-PAGE and quantitated using densitometry. Here, we demonstrate that UV quantitation of reverse-phase HPLC separated proteins provides increased accuracy and sensitivity, can be fully automated, and allows one to perform F-actin competition assays on similar sized proteins.
