Interpretive Summary:

Technical Abstract: Two-dimensional difference gel electrophoresis (2-D DIGE) is the most effective method utilized to carry out gel-based quantitative proteomics. Unfortunately, the most popular image analysis software used to process DIGE images (DeCyder) produces picking coordinates in a format that is incompatible with most commercially available spot picking robots. To achieve the full promise of proteomic research it is necessary to perform protein identification experiments on such a scale that automation is required. Thus, there is a need for transformation software to convert the DeCyder generated picking coordinates to a format compatible with commonly available robots. Here we present a protocol using 2-D DIGE, DeCyder and the ProPic spot picking robot incorporating such a program that greatly facilitates protein identification.
