Protein expression service at evitria
At evitria, our specialization in recombinant protein expression sets us apart as a trusted partner for researchers and biotech companies worldwide. Our services encompass a wide range of protein expressions, tailored to meet the exact needs of your projects.
Recombinant antibody expression service
We offer recombinant antibody expression services, delivering high-quality antibodies for your research and development needs. From sequence to antibody, our process is efficient and reliable.
Afucosylated antibody expression service
For applications requiring enhanced antibody-dependent cellular cytotoxicity (ADCC), our afucosylated antibody expression service provides antibodies with reduced fucose content, increasing their efficacy in therapeutic applications.
Fc-silenced antibody expression service
Certain applications necessitate antibodies without effector functions. Our Fc-silenced antibody expression service delivers antibodies engineered to minimize or eliminate Fc-mediated activities.
Bispecific antibody expression service
Our capabilities extend to the expression of bispecific antibodies (bsAbs), enabling you to explore innovative therapeutic strategies that engage multiple targets simultaneously. Read more here: Bispecific antibody expression service
Other protein expression services
Beyond antibodies, our platform adapts to express any secreted protein transiently. Whether you need scFvs, soluble extracellular domains, cytokines, viral proteins, or other proteins, we can deliver sterile-filtered supernatant ready for your in-house purification.
With over 900 different proteins expressed and more than 300 non-antibody projects completed, we have gained profound experience in expressing just the proteins you need. We prioritize quality and time, offering a streamlined process that can take you from sequence to antibody in just four weeks.

Our protein expression system of CHOice
Our Chinese Hamster Ovary cell expression system is the cornerstone of our protein production services. This mammalian system ensures your proteins are correctly folded and post-translationally modified, closely mimicking natural human proteins.
The CHO system allows for high expression levels and scalability, making it ideal for both small-scale research and large-scale production. With our optimized protocols and extensive experience, we deliver high-quality proteins that meet the rigorous demands of your projects – with no live animals involved in the process.
High-Throughput Antibody Production Service
Accelerate early-stage antibody discovery with parallel CHO expression of up to several hundred constructs per project.
evitria’s HTP antibody production service delivers purified, assay-ready antibodies within 4 weeks – with the same Swiss-quality analytical package used at clinical scale. No host-cell transitions, no re-optimization, no delays.
