From your protein source
Whether you are focused on lead discovery, production of identified targets for high throughput screening, or characterization of interesting gene products, Exon Biosystem is available to help you solve challenging problems.
In response to our clients diverse needs of recombinant proteins, we offer multiple expression systems to meet the requirement of our clients.

Molecular Biology Services
Customized molecular biology projects, such as gene cloning, mutagenesis, 5'- or 3'-RACE and antibody cloning and sequencing.
Recombinant Protein Expression
We provide recombinant protein production services either with bacterial expression system or mammalian expression system. Quick transient expression and high yield stable cell line.
Antibody Engineering Services
Antibody cloning from hybridoma or isotype switching or affinity maturation, exonbio provides antibody engineering services that fit your needs.
Biologics Services
With an improved Freedom vector and cGMP banked CHO cells from Invitrogen, exonbio develops high yields highly stable cell lines for biologics .By optimizing current expression system and developing novel expression systems, we have gained much expertise in expressing difficult proteins and antibodies, such as GPCR, ion channel proteins, proteases, nuclear receptors, reconbinant antibodies and recombinant virus proteins.
We routinely produce:
- Target proteins for lead discovery.
- Target proteins for rational drug design.
- Therapeutic proteins for pre-clinical trials.
- Recombinant antigens for vaccine development.
- Proteins for use in diagnostic kits.
- Proteins for structure studies.
- Proteins for functional studies/enzymatic assays.
- Protein-protein/ligand interactions studies.
- Proteins for microarrays.
- Set up of protein libraries.
- Protein variants generation and screening.
- Recombinant antibody for pre-clinical trials.
