Abstract
The adapter dynactin and the activator BicD2 associate with dynein to form the highly motile dynein-dynactin-BicD2 (DDB) complex. In single-molecule assays, DDB displays processive runs, diffusive episodes, and transient pauses. The switching rates and durations of the different phases can be determined by tracking gold nanoparticle-labeled DDB complexes with interferometric scattering (iSCAT) microscopy and using an algorithm to separate out different motility phases. Here we describe methods for purifying DDB complexes from brain lysate, labeling with gold nanoparticles, imaging by iSCAT, and analyzing the resulting trajectories.
