Briefly, ammonium acetate, (10 μL for each mCi of 111In) is added to a reaction vial containing 111In-chloride solution. Subsequently, the DOTA-J591 solution (30 mL or 0.24 mg for each mCi of 111In) is added to the reaction vial and the mixture is gently mixed and incubated at 37° C. for 20-30 min. An aliquot of the mixture is tested to determine labeling efficiency using ITLC (SG and 5 mM DTPA, pH 5). If the binding is optimal (>70%), the reaction is stopped by the addition of 10-40 mL of 5 mM DTPA.
