Figure 1

A sample of mature dendritic cells cultured in vitro for vaccination was divided into two parts, one labelled with 99mTc-HMPAO and the other with 111In-Oxine. The DC were then suspended in DC medium and cultured in vitro for 24 h (99mTc-HMPAO) and 48 h (111In-Oxine). At 0, 4, 21, 24, and 48 h, the activity of the supernatant containing the free molecule and of the pellet containing labelled cells was measured. After 24 h, a 75% and 50% loss of activity was observed for 99mTc-HMPAO-and 111In-Oxine-labelled DC, respectively.
