Figure 4a:

Flow cytometry data show ⁸⁹Zr-oxine–labeled DCs maintained their functional activity. (a) ⁸⁹Zr-oxine–labeled DCs showed upregulation of co-receptors and major histocompatibility complex (MHC) molecules comparable to nonlabeled cells (representative data of three experiments). (b) Graphs show in vivo transferred ⁸⁹Zr-oxine–labeled OVA-loaded DCs were capable of inducing activation of pretransferred antigen-specific CMFDA-labeled OT-1 T cells (representative data of three experiments).
