Differential display technology: a general guide.

The 10 years since the invention of differential display technology (DD) has produced a massive amount of literature detailing problems and improvements to the technique, successful gene expression studies and studies done using genes found through the use of DD. In this review we summarise the results of 10 years of research that has focussed on improving DD and discuss how some of the problems associated with DD can be resolved or minimised. In addition to discussing DD, we address issues related to other differential gene expression analysis techniques and try to illustrate how these techniques can be used to complement one's use of DD. This review also serves as an introduction to the taxa-specific DD review articles that are found in this issue.
