“…Labeling of fluorescent probes BPF-01 and BPF-02 with β − /γ radionuclide (iodine-131) was accomplished under a low pH reaction conditions (pH = 5–6) using a previously reported direct radioiodination procedure, with some minor variations [ 24 ]. Briefly, the probe BPF-01 / BPF-02 (1.0 mg) was dissolved in DMSO (200 μL), and then incubated with stirring for 1.0 min.…”
