  • Method to improve the sorbent efficiency of protein A chromatography using switching column with continuous feeding
    Patent number: 9024000
    Abstract: The present invention relates to a method to improve the sorbent efficiency of protein A chromatography using switching column with continuous feeding. In the chromatography method of the present invention, the increased usage efficiency of the absorbent (resin), the decreased processing time, the decreased operation cycle of column compared to that of single batch-type column, and the reduced amount of used resin are achieved and thus, the target protein can be purified at a high efficiency and a low cost.
    Type: Grant
