Non-canonical amino acids (ncAAs) are powerful tools for expanding the structural and functional diversity of proteins. By enabling precise modifications at predetermined sites, ncAA technology supports a wide range of applications in protein engineering, biopharmaceutical development, diagnostics, and synthetic biology. Alfa Chemistry provides comprehensive ncAA incorporation services, delivering reliable, high-quality solutions tailored to both research and industrial needs.

Expression System Options

To meet diverse project requirements, Alfa Chemistry supports multiple expression systems:

E. coli Expression

Cost-effective and efficient platform for high-yield production of ncAA-modified proteins; ideal for early-stage studies and structural characterization.

Mammalian Cell Expression

Suitable for complex proteins, antibodies, and membrane proteins requiring native-like folding and post-translational modifications such as glycosylation.

Cell-Free Systems

Flexible, open reaction environments that facilitate rapid optimization, high incorporation efficiency, and compatibility with toxic or unstable proteins.

Service Workflow

1) Project Evaluation – In-depth consultation to define target protein, functional requirements, and optimal ncAA type.

2) ncAA Synthesis – Preparation of ncAAs with desired functional groups for conjugation or functional enhancement.

3) Gene Design & Expression – Codon optimization, vector construction, and expression in the selected system.

4) Protein Purification & Analysis – High-purity protein recovery using affinity chromatography, SEC, or HPLC.

5) Verification & Quality Control – Incorporation efficiency and site specificity confirmed via LC-MS, SDS-PAGE, Western blot, and functional assays.

Applications
