title: Validation of alternative methods of preparing 99mTc-MAG3.
abstract: Parameters in the preparation of 99mTc-mertiatide (99mTc-MAG3) were investigated to determine the importance of total activity, activity concentration, boiling time, and delay before boiling for the radiochemical purity (RCP) and stability of the product. Satisfactory RCP results (>90%) were obtained over a range of concentrations including a dilute preparation for paediatric use. RCP was not affected by the time between the addition of pertechnetate and boiling, but low RCP (<60%) resulted when the kit was boiled for less than 10 min.
