131I-Lym-1 in Mice Implanted with Human Burkitt's Lymphoma (Raji) Tumors: Loss of Tumor Specificity due to Radiolysis

Abstract
Preliminary evaluations of 125I-labeled Lytn-1, an anti-lymphoma mouse IgG2a monoclonal antibody, demonstrated favorable tumor uptake in mice bearing human Burkitt's lymphoma (Raji) tumors. In this study, the pharmacokinetics of 125I- and 131I-Lym-1, and the dosimetry, efficacy, and toxicity of 131I-Lym-1 in Raji-tumored mice were evaluated.
