As part of the "Reliable Lab Solutions" series, "Techniques in Confocal Microscopy" brings together chapters from volumes 302, 307 and 356 of "Methods in Enzymology". It documents many diverse uses for confocal microscopy in disciplines that broadly span biology. The methods presented include shortcuts and conveniences not included in the initial publications. Techniques are described in a context that allows comparisons to other related methodologies. Methodologies are laid out in a manner that stresses their general applicability and reports their potential limitations.
