Example - Comparing 2D PAGE Gels May Suggest
Putative Spot Identification

Scientists around the world often work on similar 2D gel data
Many 2D gel image Web databases provide protein identification spot maps
Comparing samples against maps may suggest putative protein spot identification
How can we do this comparison? Through visual comparison - to be discussed
