Gene Optimization and Synthesis

ATUM is building on DNA2.0's reputation for rapid, reliable and accurate DNA synthesis. Using our proprietary GeneGPS® and VectorGPS® platforms we design constructs optimized to express in your system, whether that's a single gene in E. coli, a metabolic pathway in yeast or a complex bispecific antibody in mammalian cells.


We optimize expression constructs to maximize the yield of your protein from your expression host.


Our inducible/repressible expression systems give you control of when your gene is expressed; localization sequences direct your protein to the correct intracellular compartment.


If you have a multi-chain protein such as an antibody or bispecific, we help you to precisely control the relative expression levels of each chain.


By solving expression issues early, we help smooth and accelerate your path through process development into manufacturing.

Gene Optimization
Powered by GeneGPS®

Not all codon optimization algorithms are created equal. GeneGPS eliminates bias, incorrect assumptions and flawed optimization strategies by focusing on what matters - what has been experimentally demonstrated to improve expression!

GeneGPS begins with a training set of systematically varied synthetic gene variants, whose expression is experimentally tested in a target host. The expression data is analyzed using machine learning to develop a gene design algorithm for that host. Genes designed using GeneGPS reliably outperform genes designed using alternative methods.

The GeneGPS technology is protected by issued US patents 7561972, 7561973, 8126653, 8401798 and pending applications.

We have built GeneGPS optimization algorithms for many bacterial, yeast, insect, plant, fungal and mammalian expression hosts. We continue to develop GeneGPS for novel expression hosts.

Gene variants optimized by GeneGPS express up to 10-fold more protein in E. coli than variants created using competitors' algorithms (high CAI, matching host bias, etc.).

Vector Design
Powered by VectorGPS®

Gene optimization without vector optimization is to leave the job half done. Vector elements can improve protein solubility, reduce aggregation, direct proteins to the correct compartment, mediate genetic stability and contribute to host cell health, as well as increasing expression yield.

Our extensive Vectorology® collection of vector elements include promoters, terminators, genetic insulators, RNA processing sequences, secretion signal sequences, solubility and affinity tags, selectable markers and bacterial and eukaryotic origins of replication. With VectorGPS we combine these Vectorology elements systematically, test the resulting vectors experimentally, and use machine learning analysis of the data to identify the best combinations of elements.

We have developed many ready-to-use expression vectors with superior performance in a wide range of hosts. We continue to apply VectorGPS to design custom vectors for novel hosts and applications.

ATUM expression vectors typically outperform commercially-available vectors (pCDNA3.4, pTT5) for the transient expression of GFP in HEK293 (v1, v2), ExpiCHO (v5, v6) and in both HEK293 and ExpiCHO (v3, v4).

Complete Construct

Coupling gene optimization and vector design gives you the greatest chances of obtaining a highly performing expression construct.

A 5-fold improvement in titer of antibody in HEK293 delivered by combining vector and gene optimization.

RUSH Gene Synthesis Service

ATUM provides the fastest and most reliable gene synthesis turnaround time in the industry. From idea to bench in as little as 5 days to meet your research deadlines. Guaranteed.

Gene Length Rush Delivery (Business Days)
Rush <1kb 5 days
Rush 1kb – 2kb 10 days
Rush 2kb – 3kb 12 days
See details & restrictions below

Follow the status of your gene synthesis in real time directly in your online ATUM account.

Guarantee: ATUM will guarantee eligible genes (see Restrictions) to ship from ATUM within the above turnaround times once an order has been approved. Eligible genes that fail to meet the business day turnaround time posted will be credited with half the gene cost on a ATUM GeneCard for future orders.

Priority Service: Move your genes to the top of the queue at every step in the gene synthesis process. Not quite as fast as our signature RUSH service, but genes generally ship 20% faster than standard delivery. Actual delivery times are based on the individual gene and cloning characteristics.

Restrictions: ATUM′s turnaround guarantee is not valid for orders requiring custom cloning, low copy vectors, genes encoding high GC, stretches of homopolymers, extensive repeats or genes longer than 3kb. Turnaround times can be affected if a gene is toxic to E.coli at propagation.

Orders placed before 5:00pm PST (on USA business days) will be considered ordered on the same day.

Shipping: All orders are shipped UPS Overnight from California to arrive Worldwide in 48 hours or less. US and Canadian customers can expect genes to be delivered the day after Ship date. European, Australian and Asian customers can expect 1-2 days for shipment to arrive.

Sunny California: ATUM never offshores or outsources any gene synthesis to third parties. Rest assured that all your genes are made in sunny California, 100% accurate and intellectual property compliant.

expression host expertise

One of the most useful features of our gene design technology is the ability to optimize the codons in a protein for a specific organism, meaning we can design genes and vectors optimized for the most frequently used expression hosts. If you’re interested in a different expression host, we can work with you to develop a custom gene and vector design tool for optimized expression in your host.
