Affinity Column Chromatography for Protein Purification

By Ra_Alyvia619 03 Sep, 2022 Post a Comment

The goal of the affinity chromatography step is to separate your protein of interest from the majority of the host proteins. Alternatively amino acid sequence-specific proteases can be used to cleave off the affinity purification tag directly on the purification column ie on-column cleavage.
