[18F]PSMA-1007, a positron emission tomography (PET) tracer, specifically targets prostate-specific membrane antigen (PSMA), which is highly expressed in prostate cancer. PSMA-PET is effective especially for regional detection of biochemical recurrence, which significantly affects patient management. Herein, we established and optimized a one-step radiolabeling protocol to separate and purify
Waters has developed process handling protocols and QC procedures to ensure Waters Certified Vials meet their specified dimensions, levels of cleanlines, and adsorption properties. These rigorous 2-, 3-, and 4-step certification processes provide clean vials for the demands brought on by sensitive chromatography systems.
