Welcome to the future of biopharmaceutical R&D and Manufacturing. Our advanced metabolic-strain engineering and purification platforms enable revolutionary efficiencies in biopharmaceutical discovery and manufacturing.

Accelerate the drug discovery process using AbSci’s all-in-one protein expression platform, SoluPro™. The optimization process enables rapid expression of soluble, complex proteins in high yields, and puts the focus on screening lead candidates instead of producing them.

SoluPro™, AbSci’s next-generation E. coli expression platform, generates diverse protein products at unparalleled yields compared to current manufacturing processes. Our technologies decrease COGs, reduce production times, and significantly increase plant capacity.

SoluPro™, our all-in-one protein expression platform, produces complex proteins ranging from full-length antibodies to insulin using the simplest, best studied, and least expensive organism, E. coli.

AbSci Advantages

Next-generation E. coli chassis, SoluPro™ produces soluble, disulfide bondedactive protein without refolding

“First-of-its-kind” workflow provides  partners a high-titer cell line in 12 weeks that produces high-quality product

Rapid cell line development and elimination of viral clearance allow for gene to GMP drug substance in 6-9 months

Up to 75% reduction in drug substance costs due to high titers and reduced number of production runs

Ultra-High Yield Streamlined Protein Production


Two key innovations form the foundation of our SoluPro™ protein expression platform: a carefully engineered semi-oxidizing cytoplasm and a dual inducible promoter system that enables precision control over protein production rates. AbSci’s unprecedented approach and proprietary understanding of protein folding enables SoluPure a chromatography-free purification method that removes downstream processing bottlenecks.

This scalable downstream purification technique utilizes existing standard to remove host-cell proteins and eliminate downstream chromatography steps. Together, SoluPure™ and SoluPro™ introduce numerous efficiencies throughout biologic discovery and manufacturing by providing rapid access to therapeutic candidates, simplifying downstream purification, and achieving fermentation titers that can be measured in tens of grams per liter.

Traditionally, protein expression in E. coli is achieved either through cytoplasmic production as inclusion bodies or through secretion into the periplasmic space. SoluPro™ expresses soluble, disulfide linked proteins through production in a semi-oxidized cytoplasm.

AbSci takes advantage of the simplicity of E. coli to assemble and screen large pools of genetic diversity in parallel. Using high-throughput assays and workflows, the ideal production strain can be identified in 3 months or less. Rapid optimization of a high-titer producing strains enables pharmaceutical and biotech partners to go from gene to GMP drug substance in less than 9 months and eliminates the need for viral clearance, which results in dramatic time savings compared to CHO.

At scale, SoluPro™ creates breakthrough efficiencies in biomanufacturing, reducing the number of production campaigns or scale of bioreactor required to produce sufficient drug substance. By returning biomanufacturing to its E. coli roots, AbSci aims to replace CHO and other mammalian expression platforms as the expression host of choice.

AbSci’s high throughput workflow generates cell lines that produce folded, active protein product in as little as 3 months.

Absci collaborates with leading pharmaceutical companies to enable step-changes in productivity to their bio-pharmaceutical R&D and manufacturing.

AbSci is supported by a syndicate of experienced investors:

“People in the industry have been talking about folding protein in E. coli for years. Before it was just theoretically possible, but the SoluPro™ Platform now makes it technically possible to fold full-length antibodies and proteins in E. coli.”

Join the Team | Change an Industry

At AbSci, we defy established protein expression conventions and continually invent new technologies and approaches which introduce efficiencies and cost savings to the biotech industry. We are looking for original thinkers, accomplished and energetic scientists who have the imagination to join us and re-define what’s possible.


10 Life Science Innovators Under 40 to Watch

There is, thankfully, no age limit on innovation—you can do it at any age. But for many, “young,” counts as under 30, sometimes under 35, or even under 40, at least in terms of putting together lists of scientific innovators. Culling from a variety of lists that...
