jTraqX: a free, platform independent tool for isobaric tag quantitation at the protein level.

Many proteomic studies focus on quantitative aspects, using different stable isotope labeling techniques that require specialized software to analyze the generated data. Here we present jTraqX, an easy-to-use tool for processing and visualizing protein quantification data. jTraqX is platform independent and is compatible with all available 4-plex isobaric tags. jTraqX can be freely downloaded at http://sourceforge.net/projects/protms.
