Variant libraries from the creators of Gibson Assembly®

Choosing Codex as your synthetic DNA service provider for variant libraries, you’ll enjoy:

Fastest turnaround time

3 to 5 days (for scanning and degenerate combinatorial)​ — why wait up to 6 weeks?

Speed and savings

Superior quality

Precision libraries generated with equal amino acid representation

Applications

Protein engineering

Build and identify proteins with novel or improved stability and function

Synthetic biology

Build new metabolic pathways with different combinations of genetic elements

Antibody development

Test and identify mutant sequences with improved antigen-binding properties

Scanning libraries

We can build any scanning library, including site-saturation and alanine scanning libraries

Site-saturation Libraries (NNK, NNN)

Varied single, contiguous AA sites using degenerate bases to understand protein binding and function

Alanine Scanning Libraries

Varied single, contiguous AA sites using alanine to understand protein binding and function
