  • Title: Fluorescence imaging of single Kinesin motors on immobilized microtubules.
    Author: Korten T, Nitzsche B, Gell C, Ruhnow F, Leduc C, Diez S.
    Journal: Methods Mol Biol; 2011; 783():121-37. PubMed ID: 21909886.
    Abstract:
    Recent developments in optical microscopy and nanometer tracking have greatly improved our understanding of cytoskeletal motor proteins. Using fluorescence microscopy, dynamic interactions are now routinely observed in vitro on the level of single molecules mainly using a geometry, where fluorescently labeled motors move on surface-immobilized filaments. In this chapter, we review recent methods related to single-molecule kinesin motility assays. In particular, we aim to provide practical advice on: how to set up the assays, how to acquire high-precision data from fluorescently labeled kinesin motors and attached quantum dots, and how to analyze data by nanometer tracking.
