“We have come to depend on CIL to furnish us with high quality reagents during the past few years as our laboratory became interested in the synthesis of a series of isotopically labeled coding agents for quantification in both proteomics and metabolics.”

Dr. Fred E. Regnier | JH Law Distinguished Professor
Department of Chemistry, Purdue University






“I have been a customer of Cambridge Isotope Laboratories for over 25 years and have been very satisfied with the quality of its products, such as D2O, isotope-labeled compounds, etc. CIL is always very eager to help me and my colleagues in choosing the most appropriate materials at the most reasonable prices. It has been a pleasure to work with CIL!”
