Multiplex Quantitative Protein Expression Profiling Software

PerkinElmer Life and Analytical Sciences offers a software upgrade for its ExacTag technology, an innovative, multiplex platform for quantitative protein expression profiling by mass spectrometry (MS). V 2.0 incorporates new data visualization and analysis tools, and supports many file formats for wide MS system compatibility, and 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. ExacTag Labeling Kits utilize a family of thiol and amine reactive isobaric mass tags that offer flexibility for the quantification of protein expression of up to 10 samples simultaneously.
