• Recent ClinicalTrials: Phase II Trial of 64Cu-ATSM PET/CT in Cervical Cancer
• Recent EU Clinical Trials: Imaging of active granulomas with [18F]FDG and selected inflammatory PET tracers in pulmonary sarcoidosis
• Uses: Ultra sensitive fluorogenic substrate for ?-galactosidase, used in live cell and tissue (in vivo and in vitro) assays. This fluorescent substrate reagent could be used for monitoring kinetics of hydrolysis. For detecting Glycosidases and could be used in ELISAs, FDG substrate has also been used for identifying lacZ-positive cells with fluorescence microscopy and flow cytometry Fluorescein di(β-D-galactopyranoside) (FDG) has been used for the detection of gene expression via FACS (fluorescence-activated cell sorting).
