Fig. 5From: One-pot and one-step automated radio-synthesis of [18F]AlF-FAPI-74 using a multi purpose synthesizer: a proof-of-concept experimentTLC chromatograms of [18F]AlF-FAPI-74 with 10 mM phosphate buffered saline (pH 6.7) containing 100 mg sodium ascorbate as a formulation solution. [18F]fluoride or [18F]AlF peak is appeared near the origin (Rf = 0) and Rf of [18F]AlF-FAPI-74 is approximately 0.6–0.7Back to article page
