Our Custom Antibody Production Services
evitria is your partner for custom antibody production in CHO cells. Our expertise covers the full spectrum from early discovery through clinical-stage programs.
- Recombinant Antibody Expression Service: standard IgG production
- Bispecific Antibody Production Service: dual-targeting formats with bYlok® pairing
- Afucosylated Antibody Expression Service: enhanced ADCC for oncology
- Fc-Silenced Antibody Expression Service: reduced effector function
- High-Throughput Antibody Production Service: parallel expression for early discovery
- Recombinant Protein Expression Service: non-antibody targets in mammalian cells
Flexibility, expertise & access to innovation
Reliable outcomes in antibody development depend on flexible collaboration, deep know-how, and access to the right technologies.
With license agreements for platforms like GlymaxX®, bYlok®, and STR, you can easily integrate advanced functionalities into your constructs, without added complexity or delays.


Introducing: High-Throughput Antibody Production
Screen more candidates, decide faster. evitria’s new HTP service expresses up to several hundred CHO-based antibody constructs in parallel, delivering purified, assay-ready results in as little as 4 weeks. Designed for AI-driven discovery pipelines and early-stage screening campaigns that demand speed without compromising quality.

ANTIBODY THERAPEUTIC DEVELOPMENT
Guiding you through development challenges
We’ve been making antibodies for over 15 years, and have produced >25,000 different constructs covering different species, isotypes, subtypes, and complex assemblies. If you are looking to design a novel format, you can count on our expertise to guide you through the development process.
We at evitria are happy to step in at any stage in your project we can work from rough sketches or precise nucleotides sequences, the choice is yours.

FAQs about evitria’s Custom Antibody Production
Custom antibody production is the made-to-order development and manufacture of antibodies tailored to a specific target, format and application. At evitria, scientific consulting is part of the service from start to finish: our team helps you select the right format, expression strategy and engineering options so the antibody setup fits your program from day one.
evitria produces standard recombinant IgGs, bispecific and trispecific antibodies, afucosylated formats for enhanced ADCC, Fc-silenced antibodies with reduced effector function, high-throughput discovery panels and non-antibody proteins. All formats run on CHO-based transient expression.
CHO (Chinese Hamster Ovary) cells are the industry standard for therapeutic antibody production. They fold and post-translationally modify complex antibodies correctly, produce high yields at scale and are accepted by regulatory agencies including the FDA and EMA. Transient CHO expression allows rapid turnaround from sequence to purified protein within weeks.
Standard turnaround for transient antibody production at evitria starts at four weeks from sequence to delivered protein. Timelines vary by format and quantity: standard IgGs are fastest, bispecifics and complex formats add time for pairing and purification. Clear timelines come upfront after scope discussion.
Pricing depends on your antibody format, production scale, timeline and quality requirements. evitria provides a tailored quote within a few working days after project scope discussion. Get in touch to share your sequence and requirements.
Yes. evitria delivers custom antibodies to biotech and pharma customers in North America, Europe, Asia-Pacific and beyond. Our Swiss production facility uses validated cold-chain logistics to ensure protein integrity from packaging to arrival at your lab.
Bispecific antibodies require correct pairing of two different heavy and light chain pairs in one molecule, which is significantly harder than producing a standard IgG. evitria’s bispecific antibody production service uses bYlokî pairing technology to ensure >95% correctly assembled molecules, reducing mispairing and simplifying purification.
Afucosylated antibodies have enhanced antibody-dependent cellular cytotoxicity (ADCC) and are often used in oncology programs. Fc-silenced antibodies have reduced effector function and are used when immune activation needs to be avoided, for example in checkpoint modulation or payload delivery. evitria produces both formats through dedicated afucosylated antibody expression service and fc-silenced antibody expression service workflows.
