eBook: Bioprocess and Analytical Laboratories — Proving the Power of Data in Drug Development

Analytics pervade the entire biopharmaceutical development process — from protein characterization through biomanufacturing process optimization to final-product formulation and clinical testing. Every technical article in BPI requires data to back up the statements made, whether the topic is upstream/production, downstream processing, product development, or otherwise focused. And never mind publishing: Even more detailed documentation is required for regulatory submissions. If a company can’t back up the choices made and results obtained in development, manufacturing, and testing of its biopharmaceutical product,…

eBook: Bioinks for Bioprinting — Three-Dimensional Printing in Research and Medicine

Three-dimensional (3D) printing is one method of digital biomanufacturing for both basic biological research and translational, clinical applications. The medical field has used it to create such constructions as 3D surgical models for preoperative planning, to assist surgeons in their procedure preparations, which improves postsurgical outcomes. Examples here include generation of cleft-palate models (1), orthopedic applications (2), and cardiovascular surgical planning (3). Other forms of 3D printing for biological applications — such as 3D bioprinting — go beyond such surgical…

Accelerating Process Development Through Flexible Automated Workflows

Synthace began as a bioprocess optimization company in 2011, spun out of University College, London. The company worked on multifactorial approaches with 15–30 factors simultaneously instead of seven or eight. The work investigated genetic strain engineering factors alongside process parameters, defining deep interactions between the way strains were designed and the way they were treated in bioprocesses. Those complex experiments gave unique insight into the complexities of biological processes, but they were exceptionally taxing to plan and carryout manually. Automation…

CO2, O2, and Biomass Monitoring in Escherichia coli Shake Flask Culture: Following Glucose–Glycerin Diauxie Online

Carbon dioxide (CO2) is an important parameter in microbial cultures because it can inhibit or stimulate growth under certain conditions. In our experiment, we monitored Escherichia coli diauxie growth phases online and focused on dissolved CO2 (dCO2) and oxygen readings. We assessed diauxic growth in medium containing glycerin and glucose online with the SFR vario system (from PreSens), which optically measures oxygen, pH, and biomass in an Erlenmeyer flask. The shake flask contained an oxygen sensor spot and an optical…

BPI Lab: Essential Technologies for Development, Characterization, and QA/QC

There’s a secret hiding in plain sight: many analytical methods and technologies initially designed for pre-clinical development have equally important applications in commercial development. BioProcess International and BioTechniques, sister publications and leading journals that combined, cover the entire biopharmaceutical process, from discovery to development and manufacturing, partnered to create this special eBook, highlighting and detailing fourteen analytical technologies that provide laboratory technicians and scientists with vital information to help project managers and engineers make educated decisions that ultimately affect every…

Advancements in Characterizing Therapeutic Protein Higher-Order Structure

Electrospray-ionization mass spectrometry (ESI-MS) is a well-established tool for biotherapeutic analysis. It draws intact proteins or peptide ions into the vacuum of a mass spectrometer, where the ion mass is measured. Electrospray ion-mobility mass spectrometry (ESI-IMS) introduces ions into a low-pressure gas, where the effects of aerodynamic drag reveal their shape. This technique is just emerging as a valuable tool for characterizing intact proteins, even though for a decade it’s been the basis of a commercially available medical diagnostic test…

Enabling Faster Workflows with Protein Purification Technologies: Improvements in Chromatography and Electrophoresis

Purification of recombinant proteins is a critical step during protein therapeutics development. Protein therapeutics have a number of classifications based on their potential applications, including use as vaccines and diagnostics as well as for enzymatic, regulatory, or targeting activities (1). For all such applications, identifying and verifying protein purity is most important. Whether proteins themselves are therapeutics or the target proteins of interest, effective purification is essential in drug development. Since the introduction of recombinant proteins in the early 1980s,…

Modern Laboratory Design: Creating a Space for Effective Collaboration

When asked to envision a modern biotechnology laboratory, lay persons might describe what they’ve seen on an episode of CSI: Miami. Gleaming glass and striking colored lights might look good on television, but they are not what biological researchers need to do their work most effectively. Most of the real biological laboratories I’ve visited, in fact, have been stark, white, fluorescent-lit environments that more resemble something out of 2001: A Space Odyssey. But those are becoming passé. The newest concepts…

Cell Therapy Bioprocessing Technologies and Indicators of Technological Convergence

The cell therapy industry is undergoing a natural evolution from scientific curiosity into a commercially and clinically attractive opportunity (1). This evolution is by no means complete, and growing evidence suggests that its progression is driving significant developments in cell therapy bioprocessing — notably, convergence. Table 1:&#8 194; () Progressively, bioprocessing technologies primarily used in production of noncell-based products are being evaluated for cell therapy bioprocessing applications (2). Consequently, this process of convergence is leading to an increasing proportion of…

Effective Cryopreservation and Recovery of Human Regulatory T Cells

The list of conditions being targeted by cell therapies is rapidly growing, but commercializing cells for widespread medical use will require standardized laboratory practices. Development processes must be adapted specifically for cell-based drug products. Regulatory T-cell therapy represents a promising new frontier in the immunotherapy of autoimmune disorders, especially for patients who have been refractory to available treatments. Because of intrinsic fragility, cell therapy products can be highly sensitive to variations in manufacturing procedures. Standardization of drug-product cryopreservation and storage…
