It’s with immense pride and gratitude that we celebrate 20 years of delivering excellence in recombinant protein production for the life science community.

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.

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.

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

As Memorial Day approaches, Proteos would like to extend our warmest wishes to you and your loved ones for a safe and enjoyable weekend.

SDS-PAGE and analytical HPLC-SEC are valuable methods for detecting protein aggregation.

Previously, the importance of protein solubility during the production process was discussed. Here we continue with considerations that can improve protein solubility and reduce aggregation.

Solubility is an important consideration at any stage of recombinant protein production.

Proteos is excited to announce the expansion of our services to include intact mass analysis using LC ESI-MS.

Thank you to our valued customers for your business and support in 2022. We wish you a joyous holiday season and look forward to working with you in 2023.

Proteos would like to wish you a very Happy Thanksgiving!

Fusion proteins are often used to increase the expression and solubility of the target protein but may negatively affect the functionality of the target protein in biochemical or structural studies.
