A method is provided for trapping therapeutic or tracer agents within cells to maximize their therapeutic effect or detectability. Primary amine containing therapeutic or tracer agents are bound by reductive deamination to the active carbonyl of cellobiose. The resulting adduct is attached to a targeting agent for introduction into a selected cell. Due to the cellobiose, the adduct remains trapped within the cell to maximize therapeutic or tracer activity. Novel adducts and targeting agent-adduct conjugates are disclosed. A new double label method for measuring protein metabolism is also disclosed.
