摘要:
A process of purifying a Growth Factor Protein in a purification sequence employing chromatography characterized in that: - at least one chromatography is performed using a multimodal resin; - the Growth Factor Protein binds to the multimodal resin at a pH between 4 to 6.2, and the Growth Factor Protein is eluting at a pH > 6.3, and the elution of Growth Factor Protein is improved by addition of arginine and/or NaCI to the eluting buffer. - The multimodal resin step is followed by a yeast derived affinity ligand resin step, which results of a purity of the product >90%.
摘要:
A process of purifying or enriching coagulation FVIII employing chromatography comprising the steps of providing a fraction containing FVIII in an aqueous solution having a high ionic strength; contacting the fraction containing FVIII with a multimodal resin; optionally washing the multimodal resin having FVIII adsorbed with an aqueous washing buffer; eluting FVIII containing fractions by an aqueous elution buffer comprising at least one amino acid which is positively charged at pH 6 to 8; and optionally collecting FVIII containing fractions in purified or enriched form.
摘要:
A process for isolation and purification of a target protein by chromatography wherein the chromatography removes or depletes prions (PrP Sc ), comprising the steps of - contacting a potentially PrP SC -contaminated sample comprising a target protein with a multimodal chromatographic material; - setting buffer conditions so that the target protein is bound to the multimodal chromatographic material and whereas PrP SC is not binding to the multimodal chromatographic material; - followed by elution of the target protein.

摘要:
A process of manufacturing a prion-free Vitamin K dependent Protein in a purification sequence employing chromatography characterized in that - at least one chromatography step is performed using a multimodal resin - providing a fraction containing Vitamin K dependent Protein in an aqueous solution; - contacting the fraction containing the Vitamin K dependent Protein with a multimodal resin at a pH between 6-9; - optionally washing the multimodal resin having the Vitamin K dependent Protein adsorbed with an aqueous washing buffer to wash away contaminants and retain the Vitamin K dependent Protein, before the Vitamin K dependent Protein is eluted; - the Vitamin K dependent Protein is eluting from the multimodal resin at a pH between 6 to 9 in a buffer comprising arginine; and - optionally collecting Vitamin K dependent Protein containing fractions in purified or enriched form.
