Omicron Biochemicals, Inc. develops new and improved methods to introduce stable isotopes, primarily 13C, 2H, 15N and 18O, into biologically-important compounds. We specialize in the synthesis of labeled carbohydrates, nucleosides, and their derivatives, but will undertake the synthesis of other classes of compounds on a custom basis. Our particular strengths lie in the preparation of site-specifically labeled compounds, but we are also capable of producing uniformly labeled products.The approaches used in synthesis include chemical, chemi-enzymic, enzymic and biological methods. We also collaborate with other laboratories
