Optimized protocol for live-cell analysis of kinetochore fiber maturation in Indian muntjac cells.

Here, we take advantage of the low chromosome number (2N=6) and distinctively large kinetochores of female Indian muntjac cells to investigate the molecular mechanism underlying k-fiber maturation. We describe steps for monitoring kinetochore-microtubule dynamics over time. Specifically, we detail the combination of live-cell super-resolution CH-STED microscopy of microtubule growth events within individual k-fibers and a laser-mediated k-fiber injury/repair assay.
