Today, I did some “spot picking”. In 2D electrophoresis, you disperse proteins in a gel according to their electric charge and mass. You obtain a kind of map of proteins and, if you stain these proteins, you have a map of spots (example here). After some analysis, it could be good to identify some proteins of interest. The problem is that they are in the gel! So, today, I used a robot called “spot picker” that … picks spots representing proteins of interest out of the gel. You can see what a spot picker looks like in my proteomic set on Flickr.
