Labelling blood cells.

摘要

European Patent Specification 194843A describes a family of technetium-99m complexes of propylene amine oximes, of which that having structure 2 is typical, which have interesting brain retention properties. This invention provides a method of labelling blood cells by incubating a suspension of the cells with such a technetium-99m complex of a propylene amine oxime. For granular sites, the method has been tested clinically and found superior to 111-oxine.
