Technical Reports

The current gold standard in monoclonal antibody purification for most researchers is affinity purification with Protein A or G followed by size exclusion chromatography (SEC). Although robust and highly effective, this workflow does have critical pain points and inefficiencies, leaving researchers to feel that they must oversee every step of their workflow, not leaving their chromatography system unattended for more than a few minutes.

High purity protein is a common requirement for biochemical and structural studies. A common approach is to recombinantly express an affinity-tagged version of the protein of interest. However, this is not always a viable option. Here we showcase how the NGC Chromatography System and prepacked chromatography columns can be utilized to develop purification workflows for untagged proteins.
