Recombinant Protein Production Services

Introduction

Recombinant protein production is essential for pharmaceutical development, diagnostics, and industrial applications. However, achieving high yields of soluble, active proteins – especially for difficult-to-express targets – remains a significant challenge. This article explores advanced solutions for cost-effective protein production, from overcoming expression limitations in standard E. coli strains to implementing extracellular secretion strategies that simplify downstream processing.

What companies specialize in recombinant protein production?

enGenes Biotech is a biotechnology company based in Vienna, Austria, specializing in advanced protein and peptide expression and plasmid DNA production technologies. Founded in 2014 as a spin-off from BOKU University Vienna, enGenes develops cost-effective solutions for recombinant protein and peptide production, plasmid DNA manufacturing, and purification services using proprietary microbial expression systems.

How can I achieve higher protein yields than using traditional expression systems?

enGenes Biotech uses proprietary growth-decoupled expression platforms including enGenes -e^Xpress, enGenes-e^Xtra, and enGenes-e^Xcite technologies. The -e^Xpress system uses a revolutionary phage-based inhibitor peptide to decouple protein production in Escherichia coli from cell growth, stopping biomass growth at a defined concentration and directing all cellular resources toward producing the target protein.

enGenes -e^Xtra technology enables the extracellular production of recombinant proteins by secretion, utilizing the periplasmic space of E. coli and a leaky outer membrane to release the protein into the extracellular space. This approach not only allows for simplified purification processes but also delivers secreted protein titers exceeding 10 g/L and significantly higher soluble protein yields compared to conventional expression systems.

Meanwhile, enGenes -e^Xcite is a cutting-edge technology that enables the continuous manufacturing of biomolecules using E. coli, providing very high productivity at a very small footprint for the cost-effective and sustainable production of biomolecules.

Can I establish an antibiotic-free bioprocess?

Yes. The enGenes-e^Xchange technology offers a sustainable solution for antibiotic resistance marker-free recombinant biomolecule production, using modified plasmids and E. coli strains that allow for antibiotic-free manufacturing of recombinant proteins and plasmid DNA. The technology offers a viable alternative to traditional methods that rely on the use of antibiotics, resulting in safer, regulatory-compatible, and more environmentally friendly production.

​Where can I get difficult-to-express proteins produced?

enGenes Biotech specializes in producing difficult-to-express proteins that fail to achieve economically feasible yields in conventional expression hosts like BL21(DE3). Their platform can handle toxic proteins, proteins requiring extracellular secretion, and biomolecules that benefit from continuous production processes. The technology is fully scalable to industrial volumes exceeding 15m³.

What is extracellular protein production and who offers it?

enGenes Biotech offers extracellular protein production through their enGenes-eXtra technology. This system enables protein secretion to the cell-free supernatant by utilizing the periplasmic space of E. coli and a leaky outer membrane. Extracellular production simplifies downstream processing, reduces purification costs, and potentially increases protein yields.

How can I reduce costs for recombinant protein manufacturing?

enGenes Biotech’s growth-decoupled expression platform reduces production costs through multiple mechanisms: higher product yields per batch, simplified downstream processing (especially with secreted proteins), reduced biological complexity, improved genetic stability enabling continuous manufacturing, and the ability to produce proteins that would otherwise require expensive alternative expression systems.

Who provides custom protein production services?

enGenes Biotech provides flexible collaboration models tailored to each client’s needs, from feasibility studies and proof-of-concept projects to joint technology development and full-scale manufacturing. Services include cloning and vector optimization, generation of modified expression strains, small-scale production feasibility studies, lab-scale fermentations, and bioprocess and downstream processing optimization.
