Imaging the mitotic spindle.

ABSTRACT

The mitotic spindle, due to its striking form, has been imaged for well over 100 years. Composed largely of microtubules and chromosomes, the spindle also contains numerous proteins whose roles include biochemical and biophysical regulation of mitosis. Given the transient, dynamic nature of the spindle, the light microscope continues to be the main tool employed to unlock its mysteries. In this chapter, we will discuss modern light microscopy techniques commonly used for imaging this intricate cellular machine as well as provide examples and protocols. We will also describe some biological preparations and experimental regimes for investigation of the mitotic spindle.
