Confocal image of a mitotic spindle in a dividing cell. The spindle is shown in yellow and the surrounding actin cytoskeleton is in blue. Images were acquired using a 100X NA 1.4 phase objective lens and a Perkin Elmer spinning disc confocal scan head. A Hammamatsu Orca ER cooled CCD camera was used to collect images. Image collection was driven using Metamorph software. Complete Z-series of images were collected and deconvolved using AutoQuant software. The image is a maximum intensity projection of a subset of the entire Z-stack; the same subset of the Z-stack is used in each channel. Sixth Prize, 2007 Olympus BioScapes Digital Imaging Competition.
