The highest [89Zr]Zr-N-sucDf-NNV003 tumor-to-blood ratio of 1.9 (± 0.3) and 1.9 (± 0.5) was observed for the 10 and 25 μg total protein doses, compared to 1.3 (± 0.2) found for 100 μg [89Zr]Zr-N-sucDf-NNV003, suggesting CD37 in RAMOS tumors may be saturated by [89Zr]Zr-N-sucDf-NNV003 at higher protein doses (Fig. 3E). The gene discussed is CD37; the disease is neoplasm.
