Title (EN) METHOD FOR THE REDUCTION OF HOST CELL PROTEINS IN AFFINITY CHROMATOGRAPHY
(FR) PROCÉDÉ DE RÉDUCTION DE PROTÉINES DE CELLULES HÔTES DANS LA CHROMATOGRAPHIE D'AFFINITÉ
Abstract:
(EN) The current invention reports a method for purifying an antibody by reducing the content of a host cell protein. The method employs a wash step with a low conductivity aqueous solution in an affinity chromatography.
(FR) La présente invention concerne un procédé de purification d'un anticorps par la réduction de la teneur en une protéine de cellule hôte. Le procédé utilise une étape de lavage avec une solution aqueuse à faible conductivité dans une chromatographie d'affinité.
