BIOTINYLATED THYROXINE

A means for conveniently and accurately measuring thyroxine or thyronine present in the blood or the like is provided: a compound represented by general formula (I) below: wherein L represents a linear or branched-chain linker having 5 to 50 total atoms; X represents one or more thyroxines, thyronines, or residues of derivatives thereof, bound to the main chain and/or side chain of the linker represented by L, a conjugate in the form of the above compound bonded to an avidin protein, and an aqueous dispersion including a microparticles the surface of which is modified with the above conjugate.

Therapeutic methods utilizing naturally derived bio-active complexes and delivery systems therefor

Methods are disclosed for correcting biological information transfer in a patient in need of such therapy which comprise administration to a patient of a composition comprising a therapeutically effective amount of a biocomplex comprising at least one bioactive agent from each of the three informational blocks of biological information transfer, each agent being present in an amount sufficient to correct the biological information transfer of the patient under treatment and resulting in the resumption of normal cell metabolism, said amount being less than the buffering amount of said agent; together with a carrier therefor.
