METHOD OF SEPARATING AND PURIFYING YTTRIUM-90 FROM STRONTIUM-90

摘要

The present invention provides a method of separating and purifying Yttrium 90 (Y-90) from Strontium 90 (Sr-90). In addition, a zirconium (Zr) clean-up step for the Y-90 is provided. Uses of the Y-90 purified by the method include cancer research and treatment. Y-90 is particularly useful in cell directed therapy, e.g., where the Y 90 is attached directly or indirectly to a targeting molecule such as an antibody.
