FOLH1 and fibrosarcoma: We utilized a SWIRFI system equipped with an 808 nm laser (300 mW/cm2) to assess CJ215 uptake in male and female mice, across FoxN1nu, SCID and BALB/c mouse lines under ambient lighting conditions.41 The tested tumor lines comprised xenografted mice bearing breast (4T1, murine, orthotopic), prostate (PC3-PSMA, human, heterotopic), HT1080 (fibrosarcoma, human, orthotopic) and CT26 (colon, murine, heterotopic) tumors, Fig. 1 G.
