Fig. 1From: GMP-compliant production of [68Ga]Ga-NeoB for positron emission tomography imaging of patients with gastrointestinal stromal tumorRepresentative (radio-)chromatogram of [68Ga]Ga-NeoB quality control. Green represents the activity signal and red the UV signal. The chemical structure of [68Ga]Ga-NeoB is in the upper chromatogram. The lower chromatogram shows a zoom of the upper chromatogram for determination of non-radioactive impuritiesBack to article page
