摘要
Previous studies report that deferoxamine (DFO) binds metallic ions such as Fe3+, In3+ and Ga3+ with very high affinity. This property of DFO has been utilized to label DFO-coupled compounds with radiometals such as Ga-67 and In-111. We have studied the effect of low DFO concentrations and of different incubation conditions on the stability of the Ga-67-DFO complex. In our experience high (>5 mu M) DFO concentration appears to be critical in obtaining high radiochemical purity of such complexes. (C) 1998 Elsevier Science Ltd. All rights reserved.
