Nuclear Magnetic Resonance (NMR)
NMR Comparability Studies for Biosimilars: Ichor has priority access to the NMR facilities and high field instrumentation necessary to collect your FDA required biosimilarity data. Ichor offers fast turnaround times to make your deadlines, in addition to personalized, attentive, and thoughtful project management and bolt-on consulting and data analysis services.
High-Throughput FBDD and Binding Studies: Our services include 1H and 19F binding assays (FAXS, STD-NMR, WaterLOGSY), in addition to various 2D correlation experiments such as 1H-1H (COSY, NOESY, ROESY), 1H-15N (SOFAST-HMQC) and 1H-13C (ALSOFAST-HMQC) correlation spectroscopy.
Multiple instruments are equipped with SampleJet robots, allowing for low volume and/or 96 well plate screening formats. Also offered are services for production of isotopically enriched recombinant proteins.
Popular FBDD and Biosimilar NMR Services
Ichor offers all the cutting edge NMR experiments for Fragment-Based Drug Discovery and Biosimilar Comparability.
WaterLOGSY
A sensitive ligand-observed NMR experiment for detection of interactions between a ligand and a protein; well-established screening technique for FBDD.
Data Acquisition
Ichor offers various 1D and 2D NMR experiments from everything from small molecules to antibodies and other complex biologics:
Simple 1D experiments are available for everything from small molecule and protein QC to HTS screening (FAXS, STD-NMR, waterLOGSY).
Two dimensional 1H-15N experiments are commonly used for both protein QC (fingerprinting coupled with PCA or Mahalanobis Distance calculations), as well as various protein-protein and protein-ligand binding experiments & titrations.
Available Spectrometers (priority access):
- 500 MHz (1)
- 600 MHz (2)
- 800 MHz (1)
All equipped with triple resonance TCI CryoProbes (1H,13C,15N) for fast, high-quality data collection
Various multidimensional correlation experiments are also available. Custom pulse sequences can be developed upon request.
Two dimensional 1H-13C experiments are another commonly used technique for fingerprinting and QCing large biomolecules, including antibodies. Ichor offers isotopically enriched recombinant protein expression (2H, 13C, & 15N).
Options to facilitate screening:
- SampleJet robots (automation)
- 96-well plate format
- Low volume (65 µL)
- Temperature control
