YTTRIUM-90 CHELATION PROPERTIES OF TETRAAZATETRAACETIC ACID MACROCYCLES, DIETHYLENETRIAMINEPENTAACETIC ACID ANALOGUES, AND A NOVEL TERPYRIDINE ACYCLIC CHELATOR Page 221. In the Experimental Procedures under Radiolabeling Efficiency and Duration of Yttrium-90 Chelation, the concentrations of chelator stock and yttrium-90 stock should be micromolar. Under Dissociation of Yttrium-90-labeled Chelators a t pH 2.0, the concentration of yttrium-90 stock was 400 pM. Page 222. In Figure 2, the text in the legend should state that the yttrium-90 concentration was 200 pM and the final volume of chelation was 10 pL. Page 223. The legend for Figure 3 should state that the final concentration of chelator was 67 pM. BC950185C
