Exploiting the Concept of Multivalency with 68Ga- and 89Zr-Labelled Fusarinine C-Minigastrin Bioconjugates for Targeting CCK2R Expression

Figure 2

Cell-uptake studies of A431-CCK2R cells incubated with 68Ga-labelled mono- and multimers (a) and 89Zr-labelled counterparts (b). Blocking was performed with pentagastrin in 100-fold molar excess over the conjugate.
