Ga is produced from enriched zinc-68 target electrodeposited on copper base material which was irradiated with 15 MeV proton energy in 30 MeV cyclotron. A modified semi-automated separation and purification module was used to obtain pharmaceutical grade [Ga]GaCl in 35 ± 5 min. The quality of [Ga]GaCl produced was in accordance with Pharmeuropa 30.4. The [Ga]GaCl was utilized for the formulation of multiple doses of [Ga]Ga-PSMA-11 and [Ga]Ga-DOTATATE. The quality of [Ga]Ga-PSMA-11 and [Ga]Ga-DOTATATE were also in accordance with Pharmacopeia.
镓是从铜基底材料上用电沉积方法富集锌-68 靶材得到的，该铜基底材料曾在 30MeV 回旋加速器中用 15MeV 质子能量辐照。采用改良的半自动分离纯化模块，可在 35±5 分钟内获得医药级[Ga]GaCl。所生产的[Ga]GaCl 的质量符合 Pharmeuropa 30.4。[Ga]GaCl 用于配制多剂量[Ga]Ga-PSMA-11 和[Ga]Ga-DOTATATE。[Ga]Ga-PSMA-11 和[Ga]Ga-DOTATATE 的质量也符合药典标准。
