Abstract

Confocal scanning-laser microscopy combined with sophisticated image-processing techniques allow the cell biologist to explore the three-dimensional infrastructure of the cell, thus conferring a high degree of precision in localization experiments. This chapter discusses some of the inherent problems in preservation of biological specimens so that reliable data can be acquired with a confocal fluorescence microscope. The methodology is the result of an effort to study the genesis of epithelial polarity in the Madin-Darby canine kidney (MDCK) cell line. While specific methods have been developed to study these particular cells, the lessons learned about their preservation should be widely applicable. A description of the confocal principle introduces basic concepts of confocal fluorescence microscopy. One can then understand how images are recorded and how the information may be interpreted.
