P. fluorescens serves as an attractive expression host for the production of stable and biologically active antibody fragments. A proprietary strain of P. fluorescens has been specifi cally developed as a protein production platform to enable rapid identification of strains capable of expressing high titers of soluble, active protein, and refl ects the additional sophistication required of engineered antibody derivatives being developed today. PfÄ“nex Expression TechnologyTM employs a toolbox of defined P. fluorescens strains containing custom-designed combinations of genetic elements…
