Abstract
The invention relates to a .sup.99m Tc-labeled liposome encapsulated protein and to a highly efficient method of radiolabeling liposome encapsulated protein. In particular, a .sup.99m Tc carrier is used to label preformed liposome-encapsulated hemoglobin. The liposome-encapsulated .sup.99m Tc labeled hemoglobin is highly stable in vitro and in vivo and is suitable for a variety of clinical uses, including biodistribution imaging studies. The invention also relates to a method of using technetium-.sup.99m labeled liposome encapsulated hemoglobin to label neutrophils. A kit method which could be used for the convenient preparation of .sup.99m Tc-labeled liposome encapsulated hemoglobin for clinical use is also disclosed.
