Scientific progress depends on the expertise, reagents and technologies behind every experiment.
We are Fortis Life Sciences
Fortis was established in 2020 to create a more unified and scalable approach to supporting modern research and development.
Together, Fortis companies provide capabilities across antibodies, diagnostic components, molecular biology reagents, engineered nanoparticles, viral vector platforms, lyophilization and manufacturing — so you can work with greater continuity across complex scientific workflows.
Work that once required multiple suppliers can now move forward with one partner: stronger technical alignment, a more stable supply chain, and support across discovery, translational research, and advanced biologics development.
For more than fifty years, Bethyl has manufactured antibodies, proteins, and immunoassay kits in-house in Montgomery, Texas — tested for specificity and reproducibility across flow cytometry, spatial biology, and ELISA platforms.
Abcore's VHH single-domain antibody discovery, built on phage display screening, addresses difficult and emerging targets across research, therapeutic, and diagnostic programs.
Arista supplies highly characterized antibodies, antigens, and controls purpose-built for point-of-care and lateral flow diagnostics — backed by conjugation and assay development across infectious disease, fertility, and toxicology testing.
Once a target is identified, researchers confirm what happens when a gene is activated, silenced, or delivered. Vector Biolabs' catalog and custom AAV and adenoviral vectors supply that functional step — moving a hypothesis toward a therapeutic candidate.
As diagnostics and therapeutics moved toward smaller, more targeted mechanisms, nanoComposix added the materials science to match: engineered nanoparticles characterized for targeted delivery and enhanced diagnostic signal.
Antibody and nanoparticle development depend on the molecular biology tools underneath them: enzymes, master mixes, and recombinant proteins — at production scale, supporting genomic and diagnostic workflows.
IPOC's lyophilization expertise stabilizes molecular and immunodiagnostic reagents for global distribution — extending Fortis' reach to labs and patients well beyond the range of a cold chain.
Decades of hands-on experience across antibody development, molecular biology, and nanoparticle engineering help you move from a difficult target to a validated result.
Contact UsCustom antibody development, VHH and phage display discovery, conjugate and assay optimization, and bulk or OEM production — the complex steps of your workflow go to specialists who have solved them before.
Our ServicesAdvance your programs with products developed, validated, and continually expanded in-house — backed by our Farm-to-Bench production model and rigorous quality controls.
Our Products“We've been consistently pleased by Bethyl's initial candidate success rate. They are creative in their workflows, responsive to our inputs, and a great group to work with overall. We're now engaged in multiple projects, with multiple anti-PTM clones about to be launched as formal genomic mapping reagents.”
“Fortis immunize multiple rabbits, all screened for antibodies. They perform the screenings at the end of the immunization process and provide a distribution of the best potential candidates. Their proprietary antigen preparation protocols successfully generate antibodies for targets that have been unsuccessful for us with other companies in the past.”
“It was nice to see high yields with Fortis' rabbit campaign. The process was very easy because they had already cloned each B cell, so they could go back to them and produce more antibodies to increase yields.”
Trusted brands standing shoulder to shoulder to accelerate the future of scientific progress.
