Scale-up of protein purification: downstream processing issues

The concept of measuring CV/h is especially useful in affinity chromatography where the residence time determines the capacity independent of scale or bed height. In a recent multidimensional scale-up study, CV/h was used to perform a 20-fold scaling from lab- to pilot scale. It is also useful for many ion exchange, … See more Keeping a constant residence time is a well-established strategy when scaling up a chromatography step. Typically, this is achieved by keeping the bed height and linear flow velocity … See more Rather than strict adherence to constant linear velocity (cm/h), you can try measuring column volumes per hour (CV/h) for increased flexibility (1). This approach gives … See more Let’s put this alternative approach to the test. As an example, assume we want to do a 300-fold scale-up of mass load starting with a column with a diameter of 26 mm.
