Accelerating Recombinant-Antibody Fragment Production Using Bacterial and Mammalian Cell-Free Protein-Synthesis Platforms
Shakiba Nikfarjam, PhD, Postdoc, Lawrence Livermore National Lab
We developed a hybrid cell-free protein synthesis platform using E. coli and mammalian lysates to rapidly produce functional recombinant antibody fragments within hours. This workflow supports high-throughput expression of scFvs and Fabs and enables direct binding analysis using fluorescence correlation spectroscopy (FCS) without purification. By combining fast production with quantitative microanalysis, the platform accelerates early antibody discovery, reduces material and time burdens, and offers a flexible alternative to traditional cell-based expression for expanding recombinant protein engineering capabilities.
Exploiting High-Throughput Capabilities to Produce Optimal Humanized Antibodies
Kathryn Armour, PhD, Principal Scientist, Biologics Discovery & Development, LifeArc
Humanization of conventional and single-domain antibodies to produce stable, developable molecules is critical for clinical use. Our design process generates an array of humanized versions for each parent variable region, and high-throughput capabilities allow efficient expression and assaying of the hundreds of heavy-light combinations. Interrogating a variant matrix can improve on parental properties through optimization of binding, function, developability, and human identity, thus pinpointing lead candidates suitable for the clinic.
FEATURED PRESENTATION: Repressing Expression of Difficult-to-Express Recombinant Proteins During the Selection Process Increases Productivity of CHO Stable Pools
Jean-Sebastien Maltais, PhD, Research Officer, Medical Devices, National Research Council Canada
Many next-generation therapeutics remain intrinsically challenging to produce in CHO cells. We exploited a cumate-inducible CHO platform allowing reduced expression of various classes of r-proteins during selection of stable pools. Fed-batch productions showed that pools generated without cumate (OFF-pools) were significantly more productive. Cell viability was lower and pool recovery was delayed during selection of ON-pools (mimicking constitutive expression), suggesting that high producers were likely lost or overgrown by faster-growing, low-producing cells. Using an inducible system to minimize r-protein expression during pool selection can contribute to reducing cellular stresses, including ER stress and metabolic burden, leading to improved productivity.
Moira Monika Schuler, Global CMC & Tech Bus Dev Mgr, Wacker Biotech
In vivo gene therapy utilizing targeted lipid nanoparticle (LNP) systems represents a transformative approach in the development of advanced therapies. The success of these targeted LNP-based therapies is fundamentally dependent on the availability of high-quality antibodies and antibody fragments, which serve as essential moieties for precise delivery and targeting. Manufacturing of these antibodies is central to the success of this strategy.

Dermal Peptide Solutions: Unique Challenges for Actives and Delivery
Jay Sarkar, PhD, Co-Founder, reThink64 Bionetworks
Peptide actives are gaining traction, not just for internal medicine, also for topical usage. The challenges for dermal delivery, however, puts constraints on the types of peptide solutions that can be produced so far. Pushing the boundaries with longer sequences with more diversified targets necessitates the tandem evolution of large-molecule delivery solutions. This talk will review existing solutions as well as introduce novel modalities for dermal peptide products.
Applying Biologic CMC Principles to Peptide Production: From Discovery to Development
Steven Bowen, PhD, Principal Consultant, ELIQUENT Life Sciences
This talk explores how biologic CMC (Chemistry, Manufacturing, and Controls) principles can be effectively applied to peptide production across the discovery-to-development continuum. By leveraging established frameworks from biologics, we demonstrate strategies to enhance peptide quality and regulatory readiness. Key topics include process development, analytical characterization, and quality control, emphasizing a streamlined approach to accelerate peptide therapeutics toward clinical success.

Advances and Challenges in Plant-Based Expression Systems for Therapeutic Proteins
Plant-based expression platforms have emerged as a promising biotechnological alternative for producing therapeutic recombinant proteins requiring complex post-translational modifications. This work will present the current landscape and the key advantages and current challenges of plant-based systems, focusing on growing and engineering the plants to produce the desired product. It will also highlight emerging technologies designed to overcome these obstacles, alongside recent advances that increase the viability and scalability of these platforms to produce innovative, effective, and affordable biopharmaceuticals.
Metabolome Profiling Reveals Host Factors Driving Soluble Expression of Disulfide Rich Proteins in E. coli
Snehal Ganjave, PhD, Specialist, Pharmaceutical Chemistry, University of California- San Francisco
Recombinant production of disulfide rich proteins in E. coli is hindered by host redox imbalance, misfolding and aggregation. In our study, we combined untargeted metabolomics of two E. coli strains (BL21 (DE3) and SHuffle) with manipulation of fusion tags (thioredoxin) and induction temperature to identify metabolic signatures associated with soluble vs insoluble expression. Our findings reveal actionable metabolome based indicators of host performance and provide a roadmap for rational expression platform design.
High-Throughput Reagent Production to Enable Biotherapeutics Discovery
Holly Schmidt, Senior Principal Scientist, Bristol Myers Squibb
Supporting biologics drug discovery for a large organization requires high-throughput techniques for expression, purification, and characterization of reagents to enable candidate exploration. High-quality extracellular domains of target proteins or chaperones are useful for many applications, including hydrogen-deuterium exchange, structural efforts, and direct binding analysis of biotherapeutics to targets by SPR. Enabling workflows, including chaperone selection and modified multi-step ÄKTA systems to produce mg-scale reagents, will be discussed.

Next-Generation Shake Flasks: Can We Reach Bioreactor-Level Performance?
Vikash Kumar, Senior Scientist, Biologics Process Research and Development, Merck
The Aero-Yield flask is a next-generation breathable shake flask fabricated from gas-permeable silicone, enabling oxygen influx and CO2 efflux across the entire surface via passive diffusion. This design increases oxygen flux by 58-fold and improves volumetric mass transfer coefficients (kLa) by up to 100%. Cultures of E. coli and Pichia pastoris showed biomass gains of 40–66% and protein yield improvements of 41–115%. With an oxygen-enriched jacket, these gains rose to 81–156% and 76–140%, respectively. Specific growth rate in the jacketed flask was comparable to 3L bioreactors. Aero-Yield bridges the gap between flasks and expensive bioreactors, offering scalable, high-yield performance affordably.
