Bioscan, located in Washington, D.C., has introduced its Flow-Count line of high-performance liquid chromatography (HPLC) radioactivity detectors for 125I-, gamma-, and beta- labeled proteins; monoclonal antibodies; and DNA. Applications include research analysis of protein mixtures, development of labeled monoclonal antibody tumor detection and therapy agents, and monitoring of iodine labeling procedures.
Flow-Count offers a range of detectors that can be matched to a desired application. An NaI (T1) scintillation detector provides high sensitivity and low background for 125I and gamma emitter detection. According to the company, levels as low as 100 DPM can be seen with use of the shielded well detector, which has 80 percent counting efficiency for 125I. In addition, a novel PIN diode, solid-state detector provides linear output for high-activity samples found in radiochemical and radiopharmaceutical synthesis labs. The miniature, remote detector can be shielded inside the hood or hot-cell, and can be used for quantitative monitoring ...
