Production of Biotherapeutics Using GlycoExpress® Expression Platform Technology

GlycoExpress® (GEX®) technology is a well-established human expression platform for the screening and production of biotherapeutics. By contrast with other human cell lines (e.g., HEK293 and Per.C6) GlycoExpress® expression platform consists of a toolbox of glycoengineered cell lines optimized for producing biotherapeutics with desired glycan structures to improve their clinical performance. Glycotope’s GEX® technology provides an established expression platform proven for different biopharmaceuticals: Antibodies of different isotypes (e.g., IgG, IgM, IgA) Defucosylated antibodies Bispecific antibodies/fragments (e.g., NK cell/T-cell recruiters) Difficult-to-express…

Novel Single-Use Systems Allow for Faster Powder Transfer and Higher Recovery Rates

Single-use powder containment is vital in today’s safety-focused manufacturing environment. Preventing product from cross-contamination and reducing airborne particulates is a major concern. Understanding how modern bag designs can increase safety and speed is essential for the industry. We looked at the ease of filling along with dispensing times and product loss. ILC Dover’s EZ BioPac® system shows a 71% decrease in filling times when measured against an industry-standard 2D bag. Because of the nonstatic film, we saw an almost 20%…

Consistency in Peptone Manufacturing: Modern Methods Make a Difference

What factors impact peptone variability? Variability can be linked to at least two critical elements: the biological raw materials and the production site. Raw materials can vary by species of animal or plant sourced, type of components (specific animal tissues as opposed to standardized materials), and geographical origins. Feeding practices also can cause variability. Within a single manufacturer, interbatch variability can be linked to the condition and age of a production site, its level of automation and sophistication, optimized production…

How Clean Is Your BSA?

Bovine serum albumin (BSA) is a critical component of many biotechnology and biochemistry systems. BSA is used in a variety of applications, including diagnostics, veterinary medical products, vaccine manufacturing, mammalian cell growth for biopharmaceutical production, and topical and ex vivo medical device applications. The impact of BSA on the performance of these systems is often overlooked and is identified as a possible root cause of variability only after extensive testing and elimination of other system components. There are many different…

Unlock Pichia: High-Level Methanol-Free Protein Production in Pichia pastoris

Pichia pastoris (Komagataella phaffii) is recognized as a highly competitive expression system for fast and economic production of recombinant proteins. Pichia offers many advantages. It is an established (FDA and EMA approved), safe (generally recognized as safe, GRAS), and highly competitive expression host with strong and effective secretory capacities often resulting in double-digit grams-per-liter product levels in culture supernatant. It combines advantageous properties of prokaryotes and mammalian cells. On one hand, Pichia cultures grow fast and can reach high cell…

Genderless Sterile Connectors: How Single-Use Connectors Can Increase Efficiency, Saving You Time and Money

Standardizing equipment in biopharmaceutical production streamlines operations, saving end users time and money. An area ripe for standardization is the use of genderless connections, those in which the connector halves are identical in design. Historically, single-use connections have involved male and female halves, but using two different parts can create several inefficiencies and complications, including Increased ordering complexity Greater risk of specifying the wrong system or connection, resulting in downtime and last-minute adjustments Longer lead times Increased stocking requirements.

The Forgotten Immunoglobulin LigaTrap™ Technologies and Advancements in IgM Purification

It’s been over 30 years since the identification and commercialization of protein A. Since its inception, protein A has served as the pinnacle purification platform for the immunoglobulin G (IgG) subclass of antibodies, both monoclonal and polyclonal forms. The introduction of protein A paved the way for researchers and large pharmaceutical manufacturers to develop and commercialize IgG-based therapeutics at both small and large scales, provided by its relative ease of use and well-characterized chromatographic attributes. Unfortunately, the gold standard affinity…
