Protein & Peptide Solutions

Proteins are the central mediators of biological function. Proper expression and precise modification can reveal molecular mechanisms, enhance the activity of drug candidates, and serve as components for diagnostic reagents or vaccine carriers. Creative Diagnostics covers endotoxin-free protein production, transmembrane protein expression, enzyme process development, and diverse peptide modification, delivering full-spectrum support from expression optimization to functional validation.
Our Services
Leveraging a mature protein production, purification, and analytical platform, we provide flexible, project-based protein and peptide services to meet varied research and development needs. We offer:
Why Choose Us
- Endotoxin Control: Dedicated production lines and strict monitoring ensure all protein products have endotoxin levels below 0.1 EU/µg.
- Transmembrane Expertise: Optimized protocols preserve native conformation and function of membrane proteins.
- Enzyme Development: Combining directed evolution with data-driven screening achieves balanced improvements in activity and stability.
- Peptide Modification: A range of chemical and enzyme-catalyzed strategies for PEGylation, fluorescent labeling, disulfide crosslinking, and more.
- Quality Assurance: Provide multidimensional analysis reports (SEC, SDS-PAGE, mass spectrometry).
- Flexible Customization: Production, purification, and functional assays tailored to project requirements for optimal cost-effectiveness.
Service Tips
- Provide your target protein or peptide sequence along with any known activity or structural information early to optimize design.
- Allow additional optimization time for transmembrane proteins and enzymes to balance conformation and activity.
- Specify any special tags (e.g., His, FLAG) or combined modifications at project initiation.
