Effective recombinant protein manufacturing hinges on the successful expression of proteins while minimizing complications, such as inclusion body formation. Inclusion bodies can disrupt the production and functionality of therapeutic proteins, impacting the downstream processing and overall yield. Understanding how to mitigate this issue is crucial for companies invested in recombinant protein expression.
Understanding Inclusion Bodies
Inclusion bodies are aggregates of misfolded proteins that typically form in host cells during the expression of recombinant proteins. These aggregates can occur for several reasons, including high levels of protein expression, suboptimal culture conditions, or issues with the host cell’s folding machinery. To avoid these challenges, fine-tuning expression conditions—such as temperature, inducer concentration, and culture media—becomes essential.
Strategies for Successful Protein Expression
To minimize inclusion body formation, consider employing low-temperature expression strategies. Lower temperatures can enhance the solubility of proteins by allowing proper folding. Additionally, utilizing engineered host cells that better cope with protein misfolding can significantly improve outcomes. Implementing co-expression systems with chaperones can also help in correctly folding recombinant proteins and reducing the formation of insoluble aggregates.
