Cambridge Isotope Laboratories Signs Distribution Agreement with FB Reagents to Sell Deuterated Phospholipids and Detergents

June 10, 2020
Cambridge Isotope Laboratories, Inc. (CIL) is proud to offer an assortment of deuterated phospholipids and detergents manufactured by FB Reagents, Ltd. These compounds are being used to solubilize isotopically labeled membrane proteins for high-field nuclear magnetic resonance (NMR) spectroscopy, and to study membrane structure by small-angle neutron scattering (SANS). FBR’s products significantly expand CIL’s current offering of deuterated lipids and detergents.
“We are excited to work with CIL to make our compounds accessible to more researchers worldwide,” says Dr. Vlado Gelev, President and Founder of FB Reagents. “Cambridge Isotopes is the most recognizable name in stable isotopes, and one of the oldest companies in the business. We have a lot to learn from them.” 
“As these products aid NMR investigations into membrane protein structure and dynamics, they will be an exciting and useful addition to our BioNMR product portfolio,” says Dr. Kevin Millis, CIL Senior Scientist. Kevin continues, “These are special molecules because the deuteration boosts the NMR signal and minimizes overlap in NMR spectra, provides contrast in SANS data, and extra selectivity in mass spectral data. Hence, they can be used in a variety of ways.”  Vlado adds, “A surprising benefit of deuteration is that the higher cost of the samples makes an already discerning customer even more critical, while it also justifies extra attention by our chemist (e.g., multiple purification steps). As a result these lipids and detergents are often of higher purity than their natural abundance analogs.”
