FOLH1 and neoplasm: Fluorescence flatbed scanning showed increased accumulation of the PSMA-N064 in human PCa tissues (mean fluorescence intensity (MFI) 76,578 ± 41,939) compared with tissue from the healthy prostate region (contralateral) (MFI 31,897 ± 12,609, p < 0.05), indicating specific uptake of the ligand in PSMA-expressing tumor tissue (Fig. 5A).
