- Title
Ultrahigh‐speed, ultrahigh‐resolution preparative separation of protein biopharmaceuticals using membrane chromatography.
- Abstract
This paper discusses ultrahigh‐speed, ultrahigh‐resolution preparative protein separation using an in‐house designed membrane chromatography device. The performance of the membrane chromatography device was systematically compared with an equivalent resin‐packed preparative column. Experiments carried out using model proteins showed that membrane chromatography gave more than four times greater resolution than the preparative column, while at the same time being more than 19 times faster. Membrane chromatography was therefore a better option, not only in terms of higher productivity but also in terms of higher product purity. Membrane chromatography was also superior in terms of resolving and presenting tracer impurity peaks in the chromatogram. Experiments carried out using monoclonal antibody samples showed that membrane chromatography was suitable for ultrahigh speed, and ultrahigh resolution fractionation of charge variants. This paper highlights and explains the need for proper device design for enabling the use of membrane chromatography for the efficient purification of protein biopharmaceuticals.
