Service Details

Gene Synthesis is a reliable and cost-effective method for obtaining customized DNA constructs with 100% sequence accuracy. As a powerful molecular biology tool, DNA synthesis is rapidly becoming a crucial part of research workflow and has transformed modern biology. De novo gene synthesis is quickly replacing the classical cloning and mutagenesis procedures and allows generation of nucleic acids where no template is available. In addition, when coupled with efficient gene design algorithms that optimize codon usage, it leads to high levels of recombinant protein expression.

GenScript's DNA synthesis technology utilizes on-site sequence optimization and oligo design followed by oligo synthesis and gene assembly to ensure 100% sequence accuracy. Our proprietary GenSmart™ Codon Optimization tool, a free, user-friendly online algorithm promises maximal functional protein expression so you are always just 1-click away to your optimal sequence! Compared to traditional molecular cloning techniques, GenScript's gene synthesis service saves both time and money while offering unparalleled top to bottom customizability. Read More »

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.
