Affinity tag removal is an important consideration for project design


Workflows for tackling challenging protein projects often utilize an affinity tag approach. In previous posts, we have discussed the purpose of utilizing affinity tags in recombinant protein production, the importance of selecting the proper tag for your specific protein target, and the importance of tag placement that can influence protein expression, purification, and functionality.  Our final post in this series will discuss removal of affinity tags.

Protein Purification - Chromatography Column and Test Tube

Why do we use affinity tags for protein production?


Proteos is committed to providing a quality foundation for drug discovery research.  While we have a great deal of experience purifying untagged proteins, it is generally preferable to employ an affinity tag to facilitate purification and detection of the protein of interest.
