Software Upgrade for Mass Spectroscopy Protein Research

Research labs that conduct quantitative protein expression profiling now have a new tool available in the form of a dedicated software update.

PerkinElmer Life and Analytical Sciences (Waltham, MA, USA) have released version 2.0 software upgrade for its patented ExacTag technology, a multiplex platform for quantitative protein expression profiling by mass spectrometry (MS).

The software is tailored to complement PerkinElmer's ExacTag labeling kits, which utilize a family of thiol and amine reactive isobaric mass tags that provide flexibility for the quantification of protein expression of up to 10 samples simultaneously. The software comprises new data visualization and analysis tools, and supports many file formats for wide MS system compatibility. Together, the labeling kits and the new software enable simultaneous comparison of two, four, seven, or 10 samples using any tandem mass spectrometer.

Dr. Richard Eglen, a vice president at PerkinElmer Life and Analytical Sciences, said, "Multiplex protein labeling and detection coupled with a powerful, versatile MS analysis software package represent an essential toolset for protein research labs. When measuring quantitative changes in protein expression, the simultaneous sample analysis afforded by multiplexing contributes to greater consistency and reproducibility of the measurements, as well as greater lab productivity, while the advanced software package gives the researchers highly-relevant, functional insights into their data.”
