The WCM CLC Nuclear Magnetic Resonance (NMR) Core Facility provides state-of-the-art biological and chemical nuclear magnetic resonance resources and services, and expertise in their analytical, structural and biochemical applications, to the Weill Cornell Medicine (WCM) community and to outside investigators. Services include sample preparation, NMR data collection and data analysis. The core facility provides consultation on project design and data analysis, and offers seminars, training and educational workshops.
Background: NMR is an essential component of structural biology since it is uniquely suited to examine changes in the conformation, structure and mobility of biomolecules using solution conditions closely approximating the biological environment. NMR is critical for chemical analysis and synthetic chemistry, is essential for characterizing and verifying chemical compounds. Basic NMR applications can be employed for assessing sample purity, chemical changes, binding events and the effects of mutations. More involved multidimensional NMR applications can be implemented for protein structure determination and dynamics investigations.
History: The NMR Core Facility was founded in 1999 to support structural biology, biochemistry, analytical and medicinal chemistry.The core became part of the WCM Core Laboratories Center (CLC) in 2015. Since this time the NMR Core has expanded four instruments with purchases made possible through NIH S10 instrumentation awards and institutional support.
Location: The NMR Core Facility has NMR instruments sited at two locations: Citigroup Biomedical Imaging center, 516 East 72nd Street S152, New York, NY, and within the Belfer Research Building at 413 East 69th Street BB000.53, New York, NY.
WCM Core Laboratories Center (CLC): The WCM CLC was established in 2015. The CLC includes core facilities that offer resources and services in genomics and epigenomics, proteomics and metabolomics, flow cytometry, imaging (e.g., optical and electron microscopy, high content screening, MRI, PET/CT, and ultrasound), synthetic and analytical chemistry, and nuclear magnetic resonance (NMR).
Open to all: The resources and services of the core facility are open to all investigators at Weill Cornell Medicine, Cornell University and Cornell-affiliated institutions. The facility also provides services to external investigators at both academic institutions and commercial enterprises.
1D and 2D NMR for chemical analysis to confirm chemical composition, characterization of reaction products, investigation of chemical impurities and chemical quantification.
NMR Data Collection and Analysis
The core provides state-of-the-art methods for collection and analysis for NMR studies of protein and peptides for analyzing structure, stability and dynamics. Projects can range from rapid 1D analysis of protein structure, or molecular characterization, to measurement of molecular size and protein dynamics, and heteronuclear NMR assignments for investigation of structural change and molecular binding interactions.
Kinetic/ Thermodynamic Analysis
Examine arrays of conditions for chemical reactions and protein stability/solubility. The core also offers the capability to test arrays of temperature and conditions characterize chemical, biochemical and protein stability.
Biomolecular Structural Analysis
Sequence specific NMR assignment of protein and biological molecule. Measurement of structural constraints, analysis of protein dynamics and stability. Assessment of molecular size by diffusion NMR.
Characterization and analysis of ligand binding to proteins, nucleic acids and membranes.
NMR Data Generation and Analysis
Available commercial and academic software for NMR data processing and spectral analysis.
The core offers consultation on NMR applications, including project design, sample preparation, data collection methods and data analysis.
Users are trained to independently collect NMR data, operate the spectrometers and analyze NMR data. Training is carried out in small groups upon request.
