Innovations in Cell Culture, Sensor Technology, and Process Control: Preparing for Industry 4.0

by

To celebrate the 20th anniversary of BioProcess International, industry suppliers were asked to respond to a questionnaire about the important technologies, trends, and manufacturing innovations that have shaaped their companies and the entire industry over the past two decades. What has been the most important scientific or technological innovation in the past 20 years of bioprocessing? I have been in the industry since the mid-1990s, and clearly the most significant evolution in biomanufacturing has been the widespread implementation of single-use…

Challenges and Benefits of Networking Process Control Manufacturing Systems: Integration to Business Systems in Industry 4.0

by and

Networking of manufacturing process control systems can lead to benefits of efficiency, increased productivity, and better facility use, leading to lower cost of goods (CoG). Furthermore, integration of manufacturing systems with manufacturing execution systems (MESs) upward to an enterprise resource planning (ERP) business system improves overall organizational efficiency. An ERP system enables optimization of intrafacility manufacturing resources. For multiple manufacturing facilities, it facilitates optimization across a company’s manufacturing network. Enabling Technologies and Systems At the enterprise resource planning level (Figure…

A UF–DF Screening System for Bioprocess Development: Efficient and Cost-Effective Process Fit and Scale-Up to Manufacturing

by , , and

Ultrafiltration and diafiltration (UF–DF) of therapeutic proteins are performed in either tangential or crossflow mode using membrane filters. UF–DF plays a critical role in both downstream and upstream processes for the biopharmaceutical industry (1). In upstream production processes, classical tangential-flow filtration (TFF) or alternating tangential-flow (ATF) systems are used in high–cell-density perfusion for protein expression by cell culture (2). TFF is used in downstream processing for UF–DF and concentration of therapeutic proteins. TFF unit operations are common in protein purification…

Single-Use Technologies: BIO Theater @ Interphex 2015

by , , , , and

Andrew Lidums (NA business development manager, Parker domnick hunter) 2:30–2:55 pm Implementing a Risk-Management–Based Approach to the Prevention of Mycoplasma Contaminations Lidums began with a recent report from Genentech, where a 150-µm long Leptospira organism from a drainage ditch outside the facility managed to penetrate 0.1-µm filters. The company solved this problem by lowering the temperature of the filtration operation, which made the bacteria more rigid and kept them from getting through. Clearly, however, contaminations happen even at large facilities.…

Measuring Pressure at Very Low Levels with High Accuracy in Single-Use Systems: Improved Performance and Single-Use System Testing

by , , and

Measuring pressure in single-use systems (SUS) has become an integral part of both upstream and downstream bioprocess operations. Articles have been published on filtration applications (1), and integration into other SUS has been widely adopted. Additionally, information is available on low-pressure applications such as how to prevent overpressurization in single-use bioreactors (2). However, as users and applications both become more sophisticated, improved performance is sought for low-pressure applications (<1 psi) such as in single-use bioreactors. The reasons are two-fold: First,…

Streamlining Downstream Process Development

by , , and

Normal-flow filtration is used throughout downstream processes for biologics including depth, sterile, and viral filtration applications. Because of its ubiquity in large-scale biomanufacturing, using the most efficient normal-flow filter media area and type can lead to significant cost savings. To determine the most effective media type and area, developers use a scaled-down process model is used in bioprocess laboratories to minimize material requirements. Constant–flow-rate filter evaluations involve direct scale-down parameters that match manufacturing-scale process conditions. This type of evaluation can…

Streamlining Downstream Process Development

by , , and

Normal-flow filtration is used throughout downstream processes for biologics including depth, sterile, and viral filtration applications. Because of its ubiquity in large-scale biomanufacturing, using the most efficient normal-flow filter media area and type can lead to significant cost savings. But determining the most effective media type and area can be time consuming, labor intensive, and complicated because of a lack of specialized laboratory-scale equipment.

The equipment commonly used in this evaluation presents several disadvantages, including poor integration of multiple components from different sources (including pressure sensors, signal conditioning, data acquisition, balances, and pumps), continuous operator monitoring, and decreased portability of most systems due to their numerous components. This white paper describes how Genentech Inc. and PendoTECH collaborated on developing an integrated filter-sizing system that addresses these challenges and aids in efficient evaluation of filter media for manufacturing-scale processes.

Adoption of Single-Use Sensors for BioProcess Operations

by , and

The increasing adoption of single-use technology in biopharmaceutical, vaccine, and cell therapy production is one indication that such technology has moved far beyond its novelty stage. Arguably, this is the preferred technology of newly developed processes. Benefits have been well documented in journals and conference presentations and have led the industry to form the Bio-Process Systems Alliance (BPSA). One current need is for process sensors that offer the same convenience as disposable bags, tubings, and filters being used. An ideal…
