OptimumGene™ - Codon Optimization

As one of the world's leading suppliers of gene synthesis services, GenScript has a proven record of dedication to innovation in our constant efforts to integrate new and updated technology into our gene expression repertoire. GenScript's OptimumGene™ Gene Design system is a proprietary gene optimization technology that can alter both naturally occurring and recombinant gene sequences to achieve the highest possible levels of productivity in any given expression system. The OptimumGene™ algorithm takes into consideration a variety of critical factors involved in different stages of protein expression, such as codon adaptability, mRNA structure, and various cis-elements in transcription and translation.

Advantages of GenScript's OptimumGene Codon Optimization

  • Significant increase in protein expression
  • Fruitful results in even the most difficult sequences: GenScript's advanced algorithms optimize highly repeated sequences, extremely long sequences, and sequences with large numbers of parameters for increased protein expression.
  • Comprehensive usage tables for optimization in any host: GenScript boasts an extensive collection of proprietary codon usage tables, allowing you to do codon optimization in any host, any time for either basic research or industrial applications. For example we have specific codon tables for organisms, such as Pichia and Sf9, which are widely used in development procedures.
  • DNA vaccine design: GenScript provides effective solutions to your vaccine needs, such as screening and optimizing parameters involved in regulating vaccinal gene expression and immunogenicity.
  • Customized solutions: The optimization can be tailored to meet your specific needs of even the most esoteric project.

    Customer Testimonial

    "I think GenScript provides absolutely excellent products in a timely fashion. I have primarily used genscript to order codon optimized artificial genes. Ordering artificial genes on their website or via Email makes this especially facile because I can simply inquire about a gene, get a quote and then get a PO#. The whole process is fast and the turnaround time for obtaining the finished product is usually less than a month. I also think their technical support are wonderful people, they have been most helpful in facilitating the process. I am so impressed with them that I have recommended them to several of my colleagues."
