Ubiquitin (NEX-UB1)
Share
NEX-UB1 is a small 8.8 kDa monomeric protein for which multiple sets of resonance assignments (BMRB database) and 3D structures (PDB database) are publicly available. This protein standard is uniformly 15N, 13C-enriched. Ubiquitin has been used as an industry-wide standard in the protein NMR field for many years.
NEX-UB1 sample formulation:
NEX-UB1: Uniformly 15N, 13C-labeled ubiquitin in 90% H2O; 10% D2O 10 mM sodium phosphate buffer, pH 6.5
