Gene Synthesis Process

Sequence optimization


Oligo synthesis


Gene assemble





The provided DNA sequence is analyzed by evaluating the GC content and repetitive sequences, and optimizing the codon sequence according to the protein expression system required. (Completed with the Quote)

To design the oligos required for gene synthesis, oligo analysis software is used to determine how to divide the gene into shorter fragments and design the oligos. The length of the oligos is usually around 100bp. Subsequently, all the oligos are synthesized in one oligonucleotide synthesizer, which is completed by the end of Night 1.

The synthesized oligos are assembled into longer fragments, typically 6-700bp, through PCR and PCR assembly. For genes less than 1.5kb, such as mAb seq, the complete gene can be obtained at this step. The fragments are then cloned into PUC57 and sequenced through fragment sequencing to verify their accuracy. For genes more than 1.5kb, a few more rounds of PCR will be used to amplify the entire gene.

The synthesized gene is cloned into a plasmid vector by either enzyme digestion or seamless cloning (Gibson).

Sanger sequencing is performed to ensure the correct sequence of the synthesized gene and enzyme digestion to verify the size of resulting DNA fragments. We guarantee 100% accuracy of the synthetic DNA sequences.

Bon Opus has provided us with excellent gene synthesis and protein expression and purification services. Their design team is always accommodating to our requests and highly detailed in their project planning. Their deliverables are also spot on. We look to Bon Opus for all our gene synthesis and protein reagent production needs.

Dr. Qian Zhang,
Scripps Research Institute

The Bon Opus team is truly efficient, experienced and reliable for gene synthesis and cloning. They have successfully helped us synthesize the VH and VL genes from a monoclonal antibody and then clone them into their antibody expression vectors. Their scientists were very attentive and responsive. They even noticed one of the aa sequences I submitted was missing two residues in the very N-terminus so that we could fix the mistake in time. The final products were delivered on time, of great quality, and at very competitive pricing. Overall, we are very satisfied with their service and will continue using their gene synthesis products.

Dr. Ying Wang,
Sorrento Therapeutics

[Bon Opus] provided us with high-quality gene fragment services, even when the sequence had high GC content or a strong secondary structure. There were no mutations involved during the sequencing of our cloned gene in the plasmids. The QC data for their gene synthesis services is exceptionally clear and helpful. I have not yet worked with another company whose data proved to be so valuable. [Bon Opus]’ service is very good overall and I would highly recommend to anyone.
