  • Patent number: 4645659
    Abstract: A packaged reagent for making Technetium-99m labelled tin colloids comprises 0.75 to 750 .mu.g stannous tin, 50 to 7000 .mu.g sodium, potassium or ammonium ion, 40 to 5000 .mu.g fluoride ion, 50 to 10,000 .mu.g of a non-toxic non-ionic surface-active agent based on poly (alkylene oxide)glycol and a container aseptically enclosing said reagent. The presence of the surface-active agent, preferably one of the Pluronic types, results in smaller sized particles being produced on addition of pertechnetate to the reagent. This results in a higher liver/spleen biodistribution ratio.
