1D/2D NMR can be used to assess sample quality, purity and stability. NMR screening can also be used to identify interacting ligands and protein partners.
Rotational correlation time is the time it takes a molecule to rotate one radian and it depends on the molecule size. Application includes: estimation of molecular weight (e.g., oligomerization) and, more recently, to detect presence of antigen in sample in liquid biopsy.
NMR can used to detect small molecule interactions with target proteins using either ligand-detected methods including saturation transfer difference (STD) and WaterLogsy, or protein-detected chemical shift perturbation studies. Ligand screening can then be done with high throughput techniques by using a micro NMR probe (30 uL sample volume) and automated NMR sample changer.
The process describes the correlation of NMR chemical shifts with specific atoms in a protein or other biomolecules. Resonance assignments enable analysis of protein structures and dynamics, as well as studies of ligand binding.
NMR can be used to give insights into protein dynamics, entropic changes due to complex formation, and allosteric effects associated with ligand binding.
Chemical shift perturbation and/or X-filtered NOESY experiments can be used to detect protein-protein or protein-ligand interactions.
NMR can be used to probe nucleic acid structure and interactions.
