Scalable Separation and Purification of M13‐Bacteriophage‐Derived Particles Containing Artificial Single‐Stranded DNA Produced by Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Single‐stranded DNA (ssDNA) solutions are promising innovations shaping the future of genetic research and medical therapies. In principle, biotechnological mass production of ssDNA can be achieved using Escherichia coli in a high‐cell density fed‐batch process by secreting phagemid particles derived from the filamentous M13 bacteriophages ...

Next‐Generation Glutamine Synthetase Expression Vector for Therapeutic Protein Manufacturing Using CHO Cells

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The glutamine synthetase expression system is widely used for therapeutic protein biomanufacturing in Chinese hamster ovary (CHO) cells. Here, we present the design of an enhanced glutamine synthetase vector for generating CHOK1SV GS‐KO stable pools that produce recombinant proteins at multigram‐per‐liter levels. We first developed a synthetic

Nuclease‐Free Scalable Purification of Physalis Mottle Virus‐Like Particles Expressed in Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Plant virus‐like particles (VLPs) are promising nanotechnology platforms, but their translation requires purification strategies suitable for large‐scale production. Here, we developed a nuclease‐free downstream process for Physalis mottle virus (PhMV) VLPs expressed in Escherichia coli, combining ammonium sulfate precipitation, low‐pH ...

Feasibility Assessment of a Single‐pH Connected Polishing Train for Monoclonal Antibody Purification Using Mildly Acidic Protein A Elution and an Acidic‐Window Anion Exchange Membrane

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Monoclonal antibody downstream processing often requires multiple pH adjustments between Protein A capture and polishing steps. These adjustments increase process complexity and make direct unit‐operation connection more difficult. We evaluated a connected post‐capture polishing block operated at approximately pH 5.0 using mild‐pH Protein A ...
