NMR spectroscopy is a key analytical technique for structure elucidation of a wide range of materials from small molecules to compounds. The technique provides detailed molecular information that allows researchers have in-depth understanding of composition, chemical structure, morphology, and dynamics. NMR is particularly useful in analysis of pharmaceuticals, screening weak-binding compounds and developing into drug-like inhibitors for drug discovery. Supported by our NMR platform, Creative Biostructure offers high quality customized services ranging from production of labeled-proteins to acquisition and analysis of high-field NMR data for researchers in science and pharmaceutical industry.

Sample preparation guideline

• Labeling with isotopes: Protein NMR spectroscopy requires isotope enrichment, such as ¹⁵N, ¹³C, ³¹P, ¹⁹F in common. Samples with other isotope are also acceptable.
• Size: The molecular weight of biomacromolecule of a NMR sample is typically less than 50 KDa for high-resolution structure elucidation. Larger proteins or complexes can be studied to identify ligand/drug-binding site or to characterize the physical state.
• Amount: For solution NMR, a sample typically contains 1-10 mg/ml or 0.3 mM purified protein in a suitable buffer; for solid-state NMR, we require larger amount of samples, please talk to our specialist for more information.
• Stability: For most in-depth studies by NMR, the protein needs to be stable for several days at room temperature for data acquisition.
