GenScript locations include Piscataway, New Jersey, Nanjing, Leiden, Tokyo, and Hong Kong. See what each site does and how to find the right one for you.
GenScript's main locations are Piscataway, New Jersey, which serves as the global headquarters, and Nanjing, China, which hosts the company's largest research and manufacturing campus. The company also operates a European headquarters in Leiden, the Netherlands, a Japanese office in Tokyo, and corporate functions in Hong Kong. Together, these GenScript locations cover gene synthesis, peptide production, protein expression, antibody services, and contract development and manufacturing.
GenScript's Headquarters in Piscataway, New Jersey
GenScript was founded in 2002 in Piscataway, New Jersey, and the company still calls that town home. GenScript USA Inc. runs a large service laboratory there, producing synthetic genes, custom peptides, recombinant proteins, and antibodies for customers across North and South America.
A New Jersey base puts the company close to a dense cluster of pharmaceutical, biotech, and academic research centers along the US East Coast. That proximity shortens shipping times for temperature-sensitive reagents and makes on-site technical support easier to arrange.
GenScript's Major Sites Around the World
GenScript Biotech Corporation operates through a group of subsidiaries, and each one covers a different region or business line. The table below summarizes the primary sites and their roles.
| Location | Country | Primary Role |
|---|---|---|
| Piscataway, New Jersey | United States | Global headquarters; gene, peptide, protein, and antibody services for the Americas |

GenScript also maintains smaller regional sales and support offices in additional markets, and its CDMO subsidiary, GenScript ProBio, operates dedicated manufacturing sites of its own. The exact roster changes as the business grows, so the official website is the most reliable source for the current list.
What Happens at Each GenScript Site
United States: Piscataway, New Jersey
The New Jersey facility handles most North American orders, including custom gene synthesis, peptide libraries, and antibody development. US-based customers also reach account managers, technical support, and quality documentation teams here.
China: Nanjing
Nanjing is the manufacturing backbone of the group, with large-scale molecular biology, peptide synthesis, and protein production capacity. Many of the reagents and services sold worldwide are produced or partially produced at this campus.
Europe: Leiden, Netherlands
Leiden serves customers in the European Union and the United Kingdom. A European base helps with customs clearance, value-added tax paperwork, and faster delivery of cold-chain shipments.
Japan: Tokyo
The Tokyo office provides Japanese-language sales, quotations, and technical support. Local staff help researchers navigate documentation requirements for imported biological materials.
How to Find the GenScript Location Nearest You
- Start with the contact page on the official GenScript website, which lists regional offices, phone numbers, and email addresses.
- Check the regional version of the site for local ordering terms, currencies, and delivery estimates.
- Existing customers can review account details and order history through genscript login on the online ordering portal.
- Ask your account manager which site would fulfill a specific order before you finalize a project timeline.
Most GenScript facilities are working laboratories rather than public storefronts. If you want to schedule a site visit or audit, contact your account representative in advance.
Why the Location Network Matters for Buyers
Where an order ships from affects cost, speed, and paperwork as much as the product itself. Domestic fulfillment typically avoids customs delays, while local support teams can answer regional regulatory questions more quickly.
- Cold-chain peptides and proteins travel better on shorter routes.
- Regional sites can issue local documentation, which simplifies import and tax handling.
- Local language support reduces miscommunication on custom projects.
GenScript's catalog and custom reagents are generally sold for research use only and are not intended for human or veterinary use without the appropriate regulatory clearance.
How GenScript Compares With Other Supplier Networks
Researchers rarely evaluate a single vendor. Buyers comparing suppliers often review asymchem locations alongside GenScript's footprint, and for peptide-heavy programs, ambiopharm locations are worth checking because AmbioPharm focuses on peptide manufacturing in the United States.
