Electron tomography of microtubule end-morphologies in C. elegans embryos. Academic Article uri icon

abstract

  • In this chapter we describe the preparation of early mitotic C. elegans embryos for the tomographic reconstruction of end-morphologies of spindle microtubules. Early embryos are prepared by high-pressure freezing and freeze-substitution for thin-layer embedding in Epon/Araldite. We further describe data acquisition, tomographic reconstruction, and 3-D modeling of microtubules in serially sectioned mitotic spindles. The presented techniques are applicable to other model systems.
