A Robust Solid-State NMR Method for Protein Backbone Assignment: Band-Selective Homonuclear Cross Polarization

4 Aug 2015

A crucial step for solid state NMR site-specific protein characterization and structure elucidation is the time-consuming resonance assignment. This application note presents a set of band-selective homonuclear cross polarization experiments to facilitate the recording of spectra and to simplify the assignment process. A detailed description of necessary parameters is given.

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.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Protein BiologyThe analysis of protein expression, identity and function is vital for many areas of life science research and drug discovery. Some of the most commonly used techniques in protein analysis include Western blotting, electrophoresis and mass spectrometry.
