Proteos Recombinant Protein Expression and Purification

Recombinant Antigens: Selecting an Expression System

5/24/2021

There are many variables to consider when producing recombinant proteins, and more specifically recombinant antigens.  These variables include construct design, affinity tags, expression system, purification scheme, formulation, and characterization.  Here we will focus on selecting an appropriate expression system for recombinant antigen production.

Affinity tag removal is an important consideration for project design

8/6/2020

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.
