ExacTag technology is a multiplex platform for quantitative protein expression profiling by mass spectrometry (MS). ExacTag Analysis Software version 2.0 offers new data visualization and analysis tools, and supports many file formats for wide MS system compatibility. The software is included with ExacTag Labeling Kits, enabling simultaneous comparison of 2, 4, 7, or 10 samples using any tandem mass spectrometer. Signal intensity measurements from low mass reporter ions generated in the collision cell of a tandem mass spectrometer and protein identification data from standard databases like Mascot or SEQUEST are used to quantify and identify proteins of interest. Version 2.0 software offers the full spectrum of data resolution and more data visualization and manipulation options to hone in or cluster results, and render as visual heat maps.
