Our bacterial systems are highly versatile and can express a broad spectrum of proteins, including enzymes, recombinant antigens, fusion proteins, and more. We optimize each project to ensure the highest possible yield and functionality of your target protein. - Customized Expression Strategies
Every project is unique, and we tailor our bacterial expression protocols to fit your specific protein production goals. We offer custom vector construction, strain selection, induction conditions, and purification strategies to ensure the best results.
Our Bacterial Protein Expression Workflow:
- Consultation and Project Design
Our process begins with a thorough consultation to understand your project requirements. We evaluate the characteristics of your target protein and recommend the most suitable bacterial expression system, vector, and conditions to optimize protein yield and functionality. - Vector Design and Cloning
Our team designs and constructs custom expression vectors to ensure efficient gene insertion and optimal expression. We offer a wide range of expression tags (e.g., His, GST, MBP) to facilitate easy purification and enhance protein solubility and stability. - Protein Expression
Using optimized bacterial expression strains, we carry out small-scale pilot expression trials to determine the best induction conditions (e.g., temperature, IPTG concentration, and time). Once optimized, we scale up the production to meet your protein quantity needs. - Protein Purification
After expression, we purify the protein using a variety of techniques, such as affinity chromatography, ion exchange, and size exclusion chromatography. Our purification processes are carefully tailored to maximize protein purity, yield, and biological activity. - Quality Control and Analysis
Each protein batch undergoes rigorous quality control testing to ensure it meets your specifications. We provide detailed analysis, including SDS-PAGE, Western blot, mass spectrometry, and functional assays, to guarantee protein purity, integrity, and activity.
