GeneArt® Site-Saturation Mutagenesis
The GeneArt® Site-Saturation Mutagenesis Service systematically replaces wild type amino acid coding sequences with sequences encoding all 19 non–wild type amino acids at the position(s) you specify. Also known as sequential permutation, site-saturation mutagenesis in combination with a powerful screening assay is the most systematic mutation strategy to identify amino acid substitutions that fulfill your protein engineering goals.
Once you’ve identified variants with beneficial substitutions, the GeneArt® Combinatorial Library Service can be used to create material for more targeted directed-evolution experiments to further optimize your protein.
Options for Site-Saturation Mutagenesis
We offer several options for sequential permutation to fit a wide array of research needs. You can choose to create variants at one or more codons, and receive constructs individually or pooled. When evaluating most of the possible 19 non–wild type amino acids is sufficient, we offer the GeneArt® Site-Saturation Mutagenesis Average 16 and GeneArt® Site-Saturation Mutagenesis Minimum 16 Services that provide individual clones encoding an average of 16 or a minimum of 16 substitute amino acids at each position, respectively.
- Constructs supplied individually are 100% sequence-verified. Pooled constructs are bulk-sequenced to verify that the nucleotide content at the requested positions is degenerate and the nonmutated regions are intact
- Variant constructs are subcloned into the vector of your choice

- Identify beneficial or detrimental amino acid substitutions
- Increase affinity, specificity, activity, heat stability, detergent tolerance, etc.
- Change substrate specificity or enantioselectivity
- Reduce homology between two related proteins (avoid IP issues)
- Identify active sites or receptor-binding sites
- Systematic identification of beneficial amino acid substitutions—check every possible variant at each position
- Structural information about the protein is not needed, but it can be beneficial
- Fewer variants to screen—no oversampling is required when all clones are delivered in separate tubes
- Fast delivery times—get your project moving quickly
- Extremely cost-efficient
