Abstract
The present invention relates to a chemical product usable as a non-radioactive carrier which comprises (1) a unit of a polyformyl compound having at least three formyl groups per molecule, (2) at least two units of an amino group-containing chelating compound bonded to the polyformyl compound by a methyleneimine linkage (--CH.dbd.N--) or a methyleneamine linkage (--CH.sub.2 NH--) between a formyl group in the polyformy compound and an amino group in the chelating compound, optionally followed by reduction, (3) at least one unit of an amino group-containing physiologically active substance bonded to the polyformyl compound by a methyleneimine linkage or a methyleneamine linkage between a formyl group in the polyformyl compound and the amino group in the physiologically active substance, optionally followed by reduction.
