The use of specific fluorescent probes, combined with confocal or multiphoton microscopy and subsequent digital analysis of the images, has greatly improved the accuracy of co-localization of macromolecules in biological samples. This article addresses some of the caveats associated with the preparation and imaging of multilabeled samples and demonstrates the use of digital methods for measuring the extent of co-localization in cells.
