Empowering antibody discovery with custom protein production

Our team specializes in antibody and antigen production, covering all stages of research. From high throughput production for early stage antibody discovery, to multigram scale for late stage characterization, we have the capabilities to accommodate your project's unique needs. Our fit for purpose workflows enable us to deliver results within an impressive timeline of just 2-3 weeks, from gene arrival to protein delivery.

We prioritize quality of our final products and implement stringent quality control to ensure the integrity, purity, and functionality of the produced proteins. Our experienced team has a track record in working with complex formats (fusion proteins, multispecific antibodies)and can provide tailored workflows for production at various scales. With focus on both quality and speed, we are your trusted partner in advancing biologics projects efficiently and effectively.

Our workflow productions

High throughput Antibody Production

Our high throughput antibody production workflow uses plate-based transient expression and semi-automated methods to express and purify various antibody formats. Ideally suited for early stage discovery, it enables screening of large panels in a time and cost effective manner.

Antibody Production

Our antibody production workflows offer full upstream and downstream flexibility to insure delivery of the highest quality material for your project. From standard to complex formats, from mg to multigram scale, we provide a solution for every research stage.

Antigen Production

Our antigen production services provide a fully customized approach, to ensure a maximum efficacy and quality of the final product. For each antigen to be produced, a thorough study of the target allows strategy alignment and a custom workflow. Our expertise and resources enable reliable and efficient production of high-quality antigens.

High Throughput Production

Unravel the potential of your panel through our efficient high throughput production and accelerate your antibody discovery project. In less than two weeks with our plate-based productions in Expi293™ cell line, we can achieve an average 300-500 μg, allowing enough amount for further high throughput functional and biophysical characterization.

Our advanced system supports diverse species, isotypes, and antibody formats making use of a versatile portfolio of purification resins such as Protein A, Protein G, IMAC for efficient purification. Experience the power of high throughput plate-based production at FairJourney Biologics.

Antigen Production

At FairJourney Biologics, our antigen production workflow provides a fully customized approach to your project’s individual needs. We have a comprehensive toolbox, with multiple expression systems (mammalian and bacterial), tags for purification and to enhance expression, various downstream capabilities and we offer a wide range of transfection volumes. With every project we conduct a thorough literature search of the desired product to decide upon the most efficient strategy/strategies to achieve the correct structure and the desired amount for each project.

Every project develops in a collaborative environment, with frequent discussions streamline decision making and the ongoing activities. Our way of working has proven to be crucial in anticipating setbacks, while keeping up with the timelines in the production of challenging targets. The same antigen can be produced in various formats with different tags, depending on its purpose. Beyond the standard production, we also provide post-processing possibilities including biotinylation, enzymatic digestion for tag removal and labelling with different dyes.
