The same applies to the internalization efficiency of 68Ga-PSMA-I&F and 177Lu-PSMA-I&F into LNCaP prostate carcinoma cells compared with 177Lu-PSMA-I&T, with all 3 compounds showing identical tracer internalization after a 1-h incubation time (37°C). This evidence concerns the gene FOLH1 and prostate carcinoma.
