A convenient Simple Method for Synthesis of Meta-iodobenzylguanidine (MIBG)
Radioiodinated meta iodobenzylguanidine (MIBG) is one of the important radiopharmaceuticals in Nuclear Medicine. [123/131I]MIBG is used for imaging of Adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. For clinical application, radioiodinated MIBG is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...

متن کاملA rapid and convenient method for the preparation and storage of competent bacterial cells.
Several effective methods for bacterial cell transformation have previously been described. These methods involve treatment of cells with CaCl2 (1-5) or cobalt hexamine chloride (6). Agents such as polyethylene glycol (PEG) have also been shown to induce bacterial cell transformation (7). We now describe a new method for the preparation of competent bacterial cells that yields high transformati...
