Figure 1.
Size exclusion profile of radiolabeled PAMAM dendrimers. G6.5COOH-125I dendrimers were characterized for absence of small molecular weight impurities by eluting on: A) PD-10 column and, B) Superose 6 column. Profiles indicate radioactivity patterns measured on a γ-counter. Tables indicate the % area under the curve (AUC) for the peaks. Na125I was eluted as a control small molecular weight radioactive compound.
