Displaying 16 results of Mycophenolic Acid Stable Isotopes Mycophenolic acid stable isotopes are a set of isotopically labeled forms of mycophenolic acid, a drug used to prevent organ transplant rejection and treat autoimmune diseases. These isotopes are chemically identical to the non-labeled form but have a specific number of stable isotopes incorporated into their molecular structure. They are used in pharmacokinetic studies, drug metabolism research, and clinical diagnostic tests to accurately measure the drug's concentration and trace its metabolism in the body.
