Variant library services
Synthetic DNA, simplified
Get variant libraries in days instead of weeks.
The speed of your research shouldn’t be limited by the speed of your library services provider. Codex DNA offers variant library services that are faster, cheaper, and better. Our expert design team will ensure that you get exactly what you need.
Order arrives in days — not weeks
Codex DNA provides the fastest library turnaround time in the industry
Save on your libraries
More cost-effective than traditional combinatorial and recombinatorial mutagenesis
Superior quality
Industry-leading accuracy with documentation showing percentage ratio of amino acid variation at each position
Scanning libraries
Codex DNA provides a wide variety of scanning libraries with varied single, contiguous amino acid sites, including site-saturation (NNN, NNK) and alanine scanning libraries. Design your own custom libraries or let our expert team guide you.
Quickly identify AA sites that are sensitive to effect
Product specifications
Product format: Linear double-stranded DNA
Output: 96-well plate; 32 variants per plate; 1 position per well
Yield: 200 ng–1 µg per position (length-dependent)
Minimum order: 32 variants
Turnaround time: As few as 5 days from order to shipment
Combinatorial libraries
Codex DNA provides a wide variety of combinatorial libraries with varied, multiple non-contiguous amino acids sites using degenerate bases to optimize protein binding and function. Design your own custom libraries or let our expert team guide you.
Identify the optimal combination for the desired effect
Product specifications
Product format: Linear double-stranded DNA
Output: 96-well plate; 32 variants per plate; 1 library per well
Yield: 200 ng–1 μg per position (length-dependent)
Turnaround time: As few as 5 days from order to shipment
Targeted libraries
Codex DNA offers targeted libraries, with specific mutations distributed over the sequence space to achieve the desired diversity. Synthesized with our patented error-correction technology, libraries have the lowest error rate in the industry, at less than 1:10,000 bp. Query target mutations singly or in parallel, with no restrictions on positioning. Design your own custom libraries or let our expert team guide you.
Query multiple amino acid positions simultaneously to evaluate and optimize impact on protein activity quickly and efficiently
