    • A method of purifying human growth hormone (hGH) from deamidated hGH, oxidized hGH or both. The method comprises the steps of forming a metal cation complexed-hGH composition enriched in native hGH under conditions wherein none or less than all of the deamidated hGH, oxidized hGH or both complex with a metal cation and, isolating the metal cation-complexed hGH composition from the deamidated hGH, oxidized hGH or combination thereof. The method can further comprise the step of releasing purified hGH from the complex. Alternatively, the metal cation-complexed hGH can be encapsulated into a biocompatible polymer for sustained release of hGH. The purification method can be performed one or more times using the hGH released from the metal cation-complexed hGH composition, depending on the purity of the hGH desired.
    • 从脱酰胺hGH,氧化hGH或两者纯化人生长激素(hGH)的方法。 该方法包括以下步骤:在不存在或少于所有脱酰胺hGH,氧化hGH或二者与金属阳离子络合的条件下形成富含天然hGH的金属阳离子复合hGH组合物,并分离金属阳离子络合的hGH组合物 从脱酰胺hGH,氧化hGH或其组合。 该方法还可以包括从复合物中释放纯化的hGH的步骤。 或者,金属阳离子络合的hGH可以包封在生物相容性聚合物中以持续释放hGH。 取决于所需的hGH的纯度,可以使用从金属阳离子络合的hGH组合物释放的hGH一次或多次进行纯化方法。
