Service details

Gene synthesis is a dependable, cost-effective technology for producing tailored DNA constructs with excellent sequence precision. DNA synthesis, as a strong molecular biology technique, is quickly becoming an essential part of the research workflow and has revolutionized modern biology.

De novo gene synthesis is rapidly replacing traditional cloning and mutagenesis processes and enables the creation of nucleic acids in situations where no template is obtainable. Using efficient gene design algorithms that optimize codon usage results in high amounts of recombinant protein expression.

To guarantee 100% sequence correctness, GenScript’s DNA synthesis process employs on-site sequence optimization and oligo design, followed by oligo synthesis and gene assembly. The unique GenSmartTM Codon Optimization tool, a free, user-friendly online algorithm, offers optimal functional protein expression, so the user is never more than one click away from the ideal sequence.

In contrast to conventional molecular cloning approaches, GenScript’s gene synthesis service saves money and time while providing unmatched top-to-bottom customization.

GenScript has the experience to assist users in meeting their DNA synthesis needs as an innovator and pioneer in gene synthesis technology, with over 700,000 completed gene synthesis projects for researchers worldwide.

DNA synthesis offers potent solutions for molecular cloning, fusion protein creation, and protein expression levels that are suitably high. GenScript, armed with unique technologies, provides professional project management services and highly configurable downstream solutions to keep the project on track.

The GenScript Edge

Plasmid preparations

Plasmid preparations from microgram to gram quantities are of research, industrial, preclinical, and GMP quality.

Vector selection

With 150+ popular commercial vectors accessible, including mammalian, yeast, baculovirus, and bacterial expression vectors, GenScript provides the industry’s widest range of IP FREE vectors.

ORF clones

The most recent version of ORF clones has been synced with GenBank. Protein-coding, expression-ready genes are available in vectors tagged for protein identification and purification.


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 number. 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.”
