July 2025 – Optimal Expression System – Part 1 – Structural Complexity

Choosing the Right Expression System Understanding the structural complexity of your protein of interest is a foundational step in selecting the optimal expression system for recombinant protein production. This choice directly impacts the success of your project, influencing protein yield, quality, and functionality. Let’s explore how structural complexity guides the selection process.  Proteins with simple…
