Flow Cytometry News: Does your lab comply with 21 CFR Part 11?

21 CFR Part 11 refers to the section in the Code of Federal Regulations (CFR) that sets forth the United States Food and Drug Administration’s (FDA) guidelines on using electronic records and electronic signatures. Chapter 21 covers all regulations pertaining to GCP (Good Clinical Practice), GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice), relating to the pharmaceutical and healthcare industries. Part 11 covers all FDA regulated issues pertaining to electronic records and electronic signatures. All computer systems that store…

Improving CHO Cell Biomanufacturing via Whole Genome CRISPR Screening

This webcast features: Jamie Freeman, PhD, Product Manager, Horizon Discovery While Horizon’s GS knockout CHO K1 cell line is rapidly becoming established as one of the best performing cell lines available for the manufacture of biotherapeutics, there is untapped potential within the CHO system. Horizon is focused on using its expertise in genome engineering techniques to modify CHO cell lines to improve their expression capacity for biomanufacturing. Historically, efforts to increase yield have primarily focused on improving media and feed,…

Viral Risk Mitigation: A Global Regulatory Perspective

The production of biologics will always have the risk of viral contamination. Manufacturers have developed a multitiered approach — tailored to individual processes — to prevent adventitious viruses from entering production processes, detect contamination in raw materials and process intermediates, and remove viruses in downstream purification. This article provides an overview of the global regulatory framework to ensure the viral safety of biologics. Past Contamination Events Past contamination events have resulted in corrective and preventative actions to reduce the risk…

The Challenge of Building Better, Lower Cost Biologic Drugs Faster

A critical factor for both the lowering in costs of development as well as costs of production for biologic therapies is to develop a cell line that grows faster and produces larger amounts of vaccines and drugs using low cost synthetically defined media. Dyadic’s industrially proven C1 gene expression platform creates a stable cell line in a shortened timeline, reducing the time from gene fragment to stable cell line by 50% when compared to CHO cells. C1 stable cell lines…

Development of a Standardized Extractables Approach for Single-Use Components: General Considerations and Practical Aspects — A Manufacturer’s Perspective

The subject of extractables for single-use bioprocess contact materials has been a subject of heated debate since roughly the summer of 2012, when the first ISPE paper was published issuing a call to action to develop a standardized extractables protocol for the industry (1). As a supplier that pioneered the science of extractables (2‒11) and has published extractables data for our products for over 20 years, Sartorius Stedim Biotech (SSB) took the opportunity to look back, take stock, rationalize, and…

Sticking In or Standing Out? Dichotomy in Vaccine Purification By Chromatography

A general vaccine purification strategy can be divided into three stages, with one or more steps for each stage. The first stage is to concentrate and isolate the target molecule quickly to remove it from conditions that could lead to its inactivation or loss. Intermediate purification seeks to remove remaining contaminants, typically using an orthogonal approach. That is followed by a polishing step in which trace impurities are removed through high-efficiency steps because those impurities usually are similar to the…

Process Analytics and Intermediate Purification of Bispecific Antibodies with a Non-Affinity Platform

The therapeutic benefits of monoclonal antibodies (MAbs) have been demonstrated in recent decades with uncontestable success as treatments for human disease. Despite MAbs’ key features such as specificity, selectivity, and safety, the format has limitations (1, 2). Bispecific antibodies may overcome number of difficulties (3). Multiple formats of bispecific antibodies have been developed, although only the κλ-body is fully human and devoid of linkers or mutations. It requires no genetic modifications of heavy and light chains and results in bispecific antibodies…

Improving Bioreactor Performance Measuring Dissolved Oxygen to Determine kLa

In recent years the biopharmaceutical industry has significantly increased the demands it makes on bioreactor systems. Efficient and reproducible production of active pharmaceuticals of high quality and in large quantities is of highest priority. However, bioprocessing is a complex topic. Numerous factors affect growth of cells in culture but are difficult to determine and interpret reliably. One of the most relevant performance parameters is the volumetric mass transfer coefficient (kLa). It describes the efficiency of gas transfer (e.g., oxygen) from…

Ask the Expert on Ceramic Hydroxyapatite Chromatography Media: How to Start

Bio-Rad’s CHT Ceramic Hydroxyapatite XT (CHT XT) calcium-affinity cation-exchange chromatography medium is used for purifying numerous types of biomolecules, with single-step clearance of impurities and aggregates in monoclonal antibody (MAb) purification. This is an easy-to-use mixed-mode medium, which is both ligand and support matrix in one. In an “Ask the Expert” webinar on 18 July 2018, Mark Snyder (manager of the process chromatography R&D applications group at Bio-Rad Laboratories) discussed its application and use at process scale, providing guidelines on…
