摘要:
The present invention relates to a novel method for improving the viral safety of liquid Factor VII compositions, in particular those comprising active Factor VII polypeptides (a Factor VIIa polypeptide).
摘要:
The present invention relates to Vitamin K-dependent protein compositions having a very low, or negligible, content of protein contaminants. The present invention also relates to method applicable in the preparation of such Vitamin K-dependent protein compositions. Such methods may either be used alone or in sequential combination with the purpose of reducing the relative content of protein contaminants. The present invention is particularly relevant in the preparation of compositions of coagulation factors selected from Factor X polypeptides (FX/FXa), Factor IX polypeptides (FIX/FIXa), Factor VII polypeptides (FVII/FVIIa), and the anticoagulant Protein C, in particular Factor VII polypeptides.
摘要:
The invention relates to methods for obtaining a protein conjugate wherein a cysteine residue of the protein serves as attachment point for the chemical moiety conjugated to the protein.
