Fig. 3From: Automated synthesis and quality control of [99mTc]Tc-PSMA for radioguided surgery (in a [68Ga]Ga-PSMA workflow)Instant thin layer chromatography of both [99mTc]Tc-nanocoll and [99mTc]Tc-PSMA. The retention factor of 99mTc-colloids is less than 0.2 and that of [99mTc]Tc-PSMA greater than 0.7Back to article page
