Improving radioimmunotargeting of tumors : the impact of extracorporeal immunoadsorption and preload in rats
In radioimmunotherapy of tumors, uptake of the monoclonal antibody (MAb) used is often too low in relation to its uptake in normal tissues. The purpose of these studies was to improve experimental tumor radioimmunotargeting with (a) extracorporeal immunoadsorption (ECIA), where excess of radiolabeled MAbs circulating in blood is removed, (b) or by preload with unlabeled MAb prior to injection of r
