Protein Standards

Cambridge Isotope Laboratories, Inc. (CIL) is pleased to offer new and exciting isotope-enriched proteins for use as standards in NMR spectroscopy. Isotope-enriched protein standards are ideal for:

• Aiding in thILV and ILVFY Protein Standardse development of new pulse sequences
• Optimizing parameters for a given pulse sequence
• Assessing spectrometer performance
• Training purposes 

High-quality, high-purity standards from Nexomics  are invaluable tools for bioNMR. Each product is accompanied by the following data:

• 1 H-15N HSQC (15N-labeled proteins)
• 1 H-13C HSQC (13C-labeled proteins)
• CO-NH projection of 3D HNCO (15N,13C-labeled proteins)
• SDS PAGE (for all labeled proteins)
• MALDI-TOF (for all labeled proteins)
• 15N-edited X-filtered 2D NOESY (NEX-XF1)

 
Maltose Binding Protein (NEX-MBP)

Maltose Binding Protein (NEX-MBP)

EX-MBP is a 44.9 kDa monomeric protein for which multiple sets of resonance assignments (BMRB database) and 3D structures (PDB database) are publicly available.
X-Filtered NOESY NMR Standard (NEX-XF1)

X-Filtered NOESY NMR Standard (NEX-XF1)

In an X-filtered experiment, only NOEs between 15N/13C-1H and 14N/12C-1H (e.g. interchain NOEs) protons are observed.
Ubiquitin (NEX-UB1)

Ubiquitin (NEX-UB1)

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.
