As one of the critical tools in molecular biology research, plasmids have a broad range of applications, such as gene cloning, expression system construction, protein production, gene therapy, vaccine development, and molecular tagging. Also, plasmids play a crucial role in gene function studies and gene editing technologies such as CRISPR-Cas9, and are an indispensable component in the fields of synthetic biology and biopharmaceuticals.

At OBiO, we can supply you a one-stop custom plasmid synthesis, vector construction to virus packaging for genomics studies.

Gene synthesis services
OBIO offers gene synthesis services at prices as low as $0.14/bp.

Vector Cloning services
Multiple vector backbones are available.

We offer highly reliable vector cloning services across various backbones. Whether you need CRISPR Cas9 plasmid vector cloning for gene editing, shRNA knockdown vectors for gene silencing, or specialized lentiviral plasmid preparation, our team delivers sequence-verified vectors tailored to your specifications.

*The cloning turnaround refers to the time from production initiation to completion.

It does not include transit time and QC of customer-supplied materials and transit time.

Plasmid preps and scales
To meet the diverse research and application needs, we offer a variety of plasmid preparation service.

FAQs of Plasmids

Do you offer downstream virus packaging after plasmid construction service?
Absolutely. As a one-stop AAV and lentivirus manufacturing CRO, we seamlessly transition your custom-cloned plasmids into high-titer recombinant virus production.

What is the typical turnaround time for gene synthesis?
The turnaround time for gene synthesis is generally limited by gene length. Genes shorter than 3,000 bp without complex or repetitive motifs can typically be synthesized within 1 to 2 weeks. For constructs exceeding 3,000 bp, or those containing repetitive sequences or high GC content, the production cycle will be extended accordingly, and the exact lead time shall be assessed on a case-by-case basis.
