In contrast, uptake of 111In-labeled IgE in the tumor showed a peak 12 h after administration at around 1.5%ID/g, spleen uptake remained between 4% and 8%ID/g throughout, and liver uptake was initially very high at 34%ID/g, progressively decreasing to 8.5%ID/g at 120 h. This evidence concerns the gene IGHE and neoplasm.
