Proteos recently upgraded its eukaryotic expression capabilities with the purchase of 4 high-capacity reach-in incubator/shaker systems built by Eberbach Corporation, Belleville, Michigan.

Affinity tag removal is an important consideration for project design

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.

Eukaryotic Signal Sequences

Eukaryotic Signal Sequences

A eukaryotic signal sequence is a series of amino acids that targets a protein to the secretory pathway.
