The chromokinesin KIF22 (Kid, kinesin-10 family) is the primary generator of polar ejection forces, which contribute to chromosome positioning and alignment in mitotic cells. Assessment of KIF22 function requires quantitative comparison of relative polar ejection forces between experimental conditions. This is facilitated by the generation of monopolar spindles to reduce the impact of bioriented microtubule attachment at kinetochores on chromosome positions and increase the dependence of chromosome positions on chromokinesin activity. Radial profile plots measure the intensity of chromatin signal in concentric circles around the poles of monopolar cells and represent an expedient quantitative measure of relative polar ejection forces. As such, this assay can be used to measure changes in polar ejection forces resulting from chromokinesin depletion or perturbation.
