Biological Science
Nuclear magnetic resonance spectroscopy (NMR) is an important spectroscopic research tool in molecular structure analysis. It can provide atomic-level molecular plane and three-dimensional structure, as well as dynamic information. With the continuous development of new technologies and methods, its research field and application scope has expanded to almost all fields of natural science.
As an expert in the field of nuclear magnetic resonance, Creative Biostructure has mastered mature NMR and related technologies, and can skillfully apply them to structural identification, conformational analysis, medical clinical detection, proteomics, metabonomics and other aspects.

Basic Principle of NMR
The chemical shift, coupling constant and relaxation rate of NMR spectrum essentially reflect the intrinsic structure and dynamics of matter. In particular, the relaxation rate contains the kinetic information from microsecond to millisecond within the molecule, and some important biological processes (such as protein folding) occur in this time scale.
Application of NMR in the Study of Protein Interaction
The interaction or combination between proteins and other biological molecules (such as DNA, RNA, polysaccharides, and drugs) is the main way to complete life activities. Because the nuclear magnetic resonance parameters (chemical shift, relaxation time, diffusion coefficient, etc.) of nuclear spin in binding and free ligand molecules are quite different, the kinetic information of protein structure change can be obtained through NMR, which is very useful for drug design and screening optimization. Moreover, NMR studies the kinetic properties of liquid protein in a close physiological environment, and the results obtained are more convincing. Our services include:

Application of NMR in Biomembrane Dynamics
Nuclear magnetic resonance technology has become an important means to study membrane structure and membrane dynamics. It is well known that the bilayer membrane structure model has successfully explained the structure and function of the membrane, but the simulation and verification of the bilayer membrane structure have encountered great difficulties. The skilled application of nuclear magnetic technology provides an effective method to solve this problem. Our services include:

Characterization of Peptide Structures and Peptide-Lipid Interactions in Membranes
Application of NMR in the Study of Metabolomics
By measuring and analyzing the urine, serum or other biological samples collected in turn within a certain time, we can get the dynamic change pattern of metabolites in organs. NMR can be used to carry out experiments under physiological conditions or close to physiological conditions within a certain temperature and buffer range without any physical separation (non-destructive, without damaging the structure and properties of the sample) and qualitative analysis of compounds, to characterize and study massive metabolic information and its change rules (metabolomics), thus obtaining rich biological information such as physiology, pathology, pharmacology, and toxicology. Our services include:
Metabolic Profiling for Molecular Complexity
