Autoradiography of excised tumor sections. A and B, autoradiographs of 1-mm sections of Dunning prostate R3227-AT1tumors from rats 48 or 72 h after injection with [77As]bavituximab. Localization of bavituximab was observed in the tumor periphery and heterogeneously throughout the tumor core. C, [77As]rituximab showed relatively little accumulation in the tumor, particularly in the central regions. The autoradiograph was exposed four times longer with [77As]rituximab to visualize the distribution. Scale shows arbitrary storage phosphor units.
