Isotopic Labeling for NMR Spectroscopy of Biological Solids
Isotopic Labeling for NMR Spectroscopy of Biological Solids;
NMR Analysis of Glycans
Nuclear magnetic resonance (NMR) spectroscopy measures the extent to which a glycan or other molecule distorts a magnetic field.
NMR Chemical Shifts of Impurities Charts
Reference or download our NMR shifts charts for the most common deuterated solvents. Proton NMR and carbon NMR tables aid chemists in separating signals of impurities that might originate from residual solvents or a reaction apparatus.
Dynamic Nuclear Polarization
Dynamic Nuclear Polarization (DNP) is a phenomenon by which high spin polarization, typically derived from a bath of free radical electrons, is transferred to a nuclear spin bath, enhancing the difference between the nuclear energy levels and thereby producing dramatically
Use of 13C Isotopes in MR Research
Dr. Pratip Bhattacharya, California Institute of Technology. "Stable isotopes have played a very useful role in MR research which involves both MRI and MRS.
NMR Deuterated Solvent Properties Reference Chart
Use this reference table to find the coupling values and chemical shifts of our NMR (deuterated) solvents. Melting and boiling points, molecular weight, density, and CAS number are also listed.
Certified Reference Materials for ¹⁹F Quantitative NMR Ensuring Traceability to “The International System of Units” (SI)
In certain cases, 1H qNMR reaches its limits, especially regarding the certification of complex and larger molecules. However, new fields of application often also bring along the presence of heteroatoms, namely 31P and 19F. We therefore introduced 3 CRMs for
Biomolecular NMR: Isotope Labeling Methods for Protein Dynamics Studies
We presents an informational article concerning biomolecular NMR and the use of Isotope Labeling Methods for Protein Dynamics Studies.
Traceable Organic Certified Reference Materials for P-31 qNMR
The use of CRMs for the NMR quantification of phosphorylated organic compounds and metabolites offers several advantages as it is based on a signal comparison of the analyte with an internal or external reference standard.
Synthesis & Characterization of ±-threo-Ritalinic Acid-D10 Hydrochloride
Methylphenidate belongs to the group of medicines called central nervous system (CNS) stimulants and is used to treat attention deficit hyperactivity disorder (ADHD).
Solid-state NMR on Larger Biomolecules
Solid-state NMR on Larger Biomolecules;
Selective Protonation of Methyl Groups in Highly Deuterated Proteins
Presenting an article about the selective protonation of methyl groups in highly deuterated proteins. In which the structural NMR studies of small proteins, a maximum number of proton chemical shifts are usually assigned and NOEs connecting large numbers of sites
NMR Reference Standards
NMR reference standards ensure proper instrument performance. Review key operational parameters for these standards such as pw90, sensitivity, resolution and line shape.
Certified Reference Materials: Synthesis and Characterization of Cocaine N-oxide HCl
Cocaine is one of the most widespread illicit drugs of abuse in the US. Cocaine N-oxide is a metabolite of cocaine formed by cytochrome P-450 mediated oxidation of cocaine.1,2
Methyl Isotope-Labeling of Proteins from NMR-Bio
Methyl groups are ideal probes for studying protein structure and function by NMR. Choose among kits for isotope labeling of a single type or multiple types of methyl groups.
