Gene Synthesis
Custom Synthesis Services for 100%-Verified Clonal DNA in 3–5 Days

Overview
Quintara provides gene synthesis service and de novo DNA synthesis support for researchers who need accurate synthetic genes, complex constructs, antibody genes, and cloned plasmids.

We deliver precision-engineered gene synthesis solutions designed to accelerate your research—from antibody discovery to large-scale synthetic biology. Our Regular Gene Synthesis supports ultra-long constructs up to 200 kb and complex sequences (high GC, repeats, toxic genes) with proprietary technology, delivered in as fast as 3 business days. For antibody-focused projects, Abgene Gene Synthesis offers rapid, flat-rate synthesis starting at $59/gene, with 4-business-day production. Both services include Sanger sequencing as standard QC for 100% sequence accuracy, with optional Nanopore full-plasmid sequencing for comprehensive backbone validation. Integrated with our in-house plasmid preparation platform and 130+ ready-to-use vectors, we provide a seamless, one-stop workflow—from design to research-ready plasmid.

What Is De Novo Gene Synthesis?
De novo gene synthesis refers to building a DNA sequence directly from a designed digital sequence rather than amplifying it from an existing biological template. For researchers, this means a gene can be designed, optimized, assembled, cloned, and sequence-verified even when the natural template is unavailable, difficult to amplify, or unsuitable for downstream experiments.

As part of a custom gene synthesis workflow, de novo DNA synthesis can support protein expression, antibody discovery, synthetic biology, CRISPR-related construct design, and custom plasmid development.

* This turnaround time is for simple genes. We will evaluate the sequence after receiving your request. If it is a complex gene, we will add extra complex fee, and the turnaround time will increase a bit.

FAQ— Custom Gene Synthesis
When to Use Custom Gene Synthesis Instead of Traditional Cloning?
A synthetic gene is needed without an available natural template.

Codon optimization is required for a specific expression host.

Multiple variants, mutants, tags, or fusion designs are needed.

The sequence contains high GC, repeats, toxic regions, or other difficult features.

A cloned plasmid is preferred instead of a linear DNA fragment.

Sequence-verified clonal DNA is needed for downstream research.

Can Quintara synthesize complex genes?
Yes. Quintara's Regular Gene Synthesis supports complex sequences such as high-GC regions, repeats, toxic genes, and ultra-long constructs up to 200 kb. Complex genes are evaluated after submission and may require additional time or fees.

What is the turnaround time for gene synthesis?
Simple Regular Gene Synthesis projects can be delivered in as fast as 3–5 business days depending on gene length. Abgene Synthesis supports eligible antibody-focused genes with 4-business-day production. Longer or complex genes may require additional time.

What QC is included with Quintara gene synthesis?
Sanger sequencing is included as standard QC for 100% sequence accuracy. Optional Nanopore whole-plasmid sequencing is available for broader plasmid validation, including insert, backbone, and junction regions.

What vector options are available?
The default cloning vector is pUC57, and Quintara also provides access to 130+ ready-to-use vectors for custom plasmid construction and downstream molecular biology workflows.

Can gene synthesis be combined with plasmid preparation?
Yes. Quintara’s in-house plasmid preparation platform supports a one-stop workflow from custom gene synthesis and cloning to research-ready plasmid DNA delivery.
