Purification of recombinant proteins is a critical step during protein therapeutics development. Protein therapeutics have a number of classifications based on their potential applications, including use as vaccines and diagnostics as well as for enzymatic, regulatory, or targeting activities (1). For all such applications, identifying and verifying protein purity is most important. Whether proteins themselves are therapeutics or the target proteins of interest, effective purification is essential in drug development. Since the introduction of recombinant proteins in the early 1980s,…

Automated Purification of Native and Recombinant Proteins Using Multidimensional Chromatography
In traditional sequential chromatography, columns are run as separate entities. The process requires significant hands-on time and constant manual intervention. By contrast, automated chromatography technology provides the same results more efficiently and reliably and frees researchers to focus on other tasks, thereby shortening protein purification times from days to hours. For drug discovery, purifying protein samples is required to generate enough materials for research experiments. But the process is complex and time consuming. It involves repeated single-column purifications, careful analysis,…
