Going Small to Achieve Success on the Commercial Scale
Conducting the required number of studies on the commercial scale is not practical; scale-down models are therefore employed to determine optimum conditions for downstream separation processes, includ…

Use of Multivariate Data Analysis in Bioprocessing
Recently, researchers have described an application of MVDA towards development and optimization of a reversed phase (RP)-HPLC method for separation of metaxalone from its hydrolytic impurities (23). …

Nurturing Knowledge from Disparate Data Streams
Spectra must be collected and separation analyses performed. The data obtained must be generated as a table, chart, or other picture that describes the results, which must then be compared to referenc…

Development of Purification for Challenging Fc-Fusion Proteins
A capillary electrophoresis system (Beckman Coulter) applied high voltage to a capillary, and the electric charge caused separation by size using an UV detector to measure absorption.

Analysis of Glycosylation in Biosimilars
The use of specific proteolytic digestion procedures, in conjunction with chromatographic separation, allows the isolation of glycopeptides, which can then be analyzed using the techniques above to de…

Selecting the Right Viral Clearance Technology
“Column chromatography will frequently be effective for virus reduction, but the degree of reduction is dependent on the resin type (mode of action), the conditions used for the separation, and the ch…
