Analyser achieves non-destructive
protein analysis
System uses Fourier transform infrared (FT-IR) spectrometer technology to non-destructively scan protein samples for structural defect and impurity analysis as well as process quality monitoring
Thermo Electron announces the launch of its new complete instrumentation package for the analysis of proteins, the Proteus protein analyser system The system is based on Fourier transform infrared (FT-IR) technology and uses a Nicolet series FT-IR spectrometer to non-destructively scan protein samples for structural defect and impurity analysis as well as process quality monitoring

Thermo Fisher Scientific's Nicolet iN10 FT-IR simplifies infrared microscopy, enabling analytical and investigative chemistry laboratories to take full advantage of the power of this technique
It combines quality instrumentation with proven methodology to provide a single source for critical data including identifying and classifying types of proteins, analysis of changes in protein over varying treatment conditions, protein monitoring during synthesis, measurements of impurities present in protein solutions, and determination of protein secondary structure.
Proteus provides pharmaceutical research organisations with the ability to develop quantitative methods to determine total protein concentration and the effects of water binding and hydrogen bonding on protein structures.
The system further discriminates good product from bad and determines factors influencing conformational changes in proteins, including improper or changing storage conditions, effects of heat on denaturation and protein secondary structure or quality, proteolytic changes in proteins, and oxidative and photo-induced protein changes.
The Proteus protein analyser system offers a number of distinct advantages, such as minimised sample preparation and handling due to the unique instrument design features.
In addition, Proteus is designed for low maintenance operation, resulting in low cost of ownership.
Thermo also provides technical support and guidance via state-of-the-art standard operating procedures and a protein analysis guidebook included in the kit.
Ideal for investigative analysis or quality control applications, spectroscopy systems from Thermo are used to determine the molecular composition of a wide range of complex samples including liquids, solids and gases.
Supported by an expansive range of applications, techniques such as infrared, Raman, UV/vis and fluorescence provide a molecular fingerprint for both qualitative and quantitative analysis.
