Product news

QIAGEN, in cooperation with Cambridge Isotope Laboratories, launches EasyXpress NMR Protein Synthesis Kits. These kits provide bench-top cell-free production of proteins labeled with stable isotopes, delivering up to 10 mg protein in a matter of hours.

The incorporation of isotopically labeled amino acids (provided from Cambridge Isotope Laboratories) is done easily and in small reaction volumes – saving costs and facilitating structural analyses of proteins using NMR and quantitation using mass spectrometry.

In conjunction with the launch, the two companies are sponsoring a contest that awards winning researchers with a free isotope-enriched protein of their choice. To enter please follow the Company article page link top right of this page. Entries will be accepted through July 15, 2010.

NMR and EPR SpectroscopyNuclear magnetic resonance (NMR) spectroscopy is used to resolve the local chemical environment of atomic nuclei with spin, revealing information on molecular structure, dynamic processes and chemical reactions of organic molecules, from proteins to synthetics. Electron paramagnetic resonance (EPR) also known as electron spin resonance (ESR) spectroscopy is used to detect and quantify paramagnetic species in a sample, including free radicals as transition metal ions. By immersing the sample in a strong magnetic field, both NMR and EPR spectrometers probe the sample with either radio waves or microwaves respectively. A range of benchtop, solid-state and time domain NMR spectrometers & EPR spectrometers are available, as well as NMR tubes, NMR solvents, software, coils, and magnets.

Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.
