A purity of BZM is analyzed by a high performance liquid Chromatography (HPLC) to know whether the purity is qualified. And a quantity of a labeled ligand ([123I]IBZM) and a quantity of a free ligand (BZM) are analyzed by a liquid chromatograph tandem mass spectrometer (LC-MS/MS). The analysis result is used for maintaining a stable and qualified imaging agent. By maintaining the imaging agent, image interferences from background and receptor number are prevented.
用高效液相色谱法(HPLC)分析 BZM 的纯度,以了解其纯度是否合格。并用液相色谱串联质谱仪(LC-MS/MS)分析一定量的标记配体([123I]IBZM)和一定量的游离配体(BZM)。分析结果用于维持稳定和合格的成像剂。通过保持成像剂的稳定性,可以防止背景和受体数量对图像的干扰。
