The invention provides an antigen or drug delivery complex containing a complex of an antigen or drug and a cationic molecule, and an anionic molecule encapsulating the same. The antigen or drug delivery complex can be used as a main component of a drug delivery system that delivers various antigens and drugs to a particular cell or organ.

Composite body for antigen or drug delivery

A radioactive iodine-labeled compound represented by the following formula (I): wherein X represents a radioactive iodine atom which may substitute at an arbitrary position on the benzene ring (preferablyI,I and the like.), n represents an integer of 1 to 3, Rand Reach independently represent a substituted or unsubstituted alkyl group, Y represents an alkylene group having 1 to 6 carbon atoms (preferably methylene group), M represents a counter ion, and m represents the number of ions required to neutralize the charge of the molecule. A radioactive iodine-labeled compound that can selectively accumulate in tumor cells or tumor tissue and a scintillation imaging agent containing the compound are provided.
