Host Cell Protein Challenges in Antibody Processing: Insights Into Persistence and Mitigation Strategies

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Persistence of HCPs remains a major purification challenge in biopharmaceutical manufacturing with direct consequences for product quality, patient safety, and regulatory compliance. Over the last two decades, deeper insights into the mechanisms driving HCP persistence have clarified why certain proteins evade removal during purification ...

Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

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

Biotechnology 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

Biotechnology 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 ...

Serotype‐Tailored Midstream and Downstream Operations to Advance the Manufacturing of Adeno‐Associated Viral Vectors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Adeno‐associated viruses (AAVs) are the leading vectors for in vivo gene therapy, fueling a growing demand for scalable and robust biomanufacturing processes. Yet, the impact of cell lysis conditions on the performance of midstream and downstream unit operations across serotypes remains poorly characterized.

Batch‐to‐Batch Optimization of pH Shifts in CHO Bioreactor Operations

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Culture pH is an important operating parameter in CHO cell cultures producing mAb since it directly affects growth and specific productivity. Mathematical models can be used to optimize the magnitude and timing of pH shifts provided that they are robust to model errors.

Design principles for vitrimers: Linking dynamic covalent chemistry, network architecture, and engineering performance

Bulletin of the Korean Chemical Society, EarlyView.
This review examines vitrimer performance from a broader perspective, considering not only dynamic covalent chemistry but also molecular structure, network architecture, and rheological behavior. These factors are discussed in relation to service and processing windows, reprocessing, repair, and engineering applications, providing a multiscale ...

Structural compatibility between β‐lactams and substrate binding pockets of IMP‐1 and NDM‐1 determines the substrate spectrum

Bulletin of the Korean Chemical Society, EarlyView.
Chemical structures of three β‐lactam classes and the substrate‐binding pockets (SBPs) of B1 metallo‐β‐lactamases (MBLs) were compared. Structural compatibility between β‐lactams and MBL SBPs correlates with enzymatic activity, providing insights into the substrate spectrum of MBLs and β‐lactam resistance.

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.
