Zusammenfassung: | The present invention relates to a method for converting a buffer through two-stage diafiltration and, more specifically, to a method for diafiltering a solution containing a protein, a method for preparing a protein preparation by using the same, and a protein preparation obtained using the same. The present invention enables fast and effective progress for the establishment of buffer conversion and concentration processes of a sample containing a protein and enables the effective production of a protein drug formulation with a desired buffer in a desired concentration. Additionally, the present invention has small variations in the pH of each stage, thereby being effective in maintaining the stability of a protein.
La présente invention concerne un procédé de conversion d'un tampon par diafiltration à deux étapes et, plus particulièrement, un procédé de diafiltration d'une solution contenant une protéine, un procédé de préparation d'une préparation de protéine à l'aide de celui-ci, et une préparation de protéine obtenue à l'aide de celui-ci. La présente invention permet une progression rapide et efficace pour l'établissement de processus de conversion et de concentration de tampon d'un échantillon contenant une protéine et permet la production efficace d'une formulation de médicament protéique avec un tampon recherché dans une concentration recherchée. De plus, la présente invention présente de faibles variations du pH de chaque étape, ce qui permet de maintenir la stabilité d'une protéine.
본 발명은 2 단계의 투석 여과를 통한 버퍼 변환 방법에 관한 것으로서, 더욱 상세하게는 단백질을 포함하는 용액의 투석 여과 방법, 이를 이용한 단백질 제제의 제조 방법 및 이를 이용한 단백질 제제에 관한 것이다. 본 발명은 단백질을 함유하고 있는 시료의 버퍼 변환 및 농축 공정을 설립하는데 빠르고 효과적으로 진행 할 수 있으며, 단백질 의약품 제형을 원하는 버퍼와 원하는 농도로 효율적으로 생산할 수 있다. 또한, 각 단계별로 pH 변동성이 적어 단백질 안정성을 유지하는데 효과적이다. |
