To enhance their performance, life science specialists require flexibility in their work and tools. The increasing diversity of bioprocess applications calls for different cultivation methods. Therefore, being able to customize processes and equipment is a significant advantage. With over 45 years of experience in customizable multi-use bioreactors, Applikon Biotechnology now provides the same flexibility with customizable single-use bioreactors. The AppliFlex ST bioreactor is a fully configurable, stirred-tank, single-use bioreactor that can be designed to specific customer demands. Using three-dimensional (3D)…

With the increase of T-cell immunotherapy research, cell therapy developers have encountered the difficulty of producing consistent, high-quality products. Approved therapies Kymriah™ (tisagenlecleucel, Novartis), Yescarta™ (axicabtagene ciloleucel, Kite Pharma), and late-phase clinical products BB2121 and UCART19 have been critiqued for presenting potential obstacles to patient access because of high costs of treatment and variable manufacturing outcomes. Manufacturing processes need to be developed to increase control over each unit step in a way that improves product consistency over the life of…

Substituting traditional glass bioreactors with single-use equipment can simplify a bioprocess workflow. Implementing single-use vessels eliminates the need for cleaning and autoclaving, thus reducing the time needed to prepare a bioprocess run and lowering contamination risk. Another advantage is that single-use vessels reduce occupational hazards associated with overweight handling (especially at larger bench scales) because plastic weighs less than glass.

Biopharmaceutical companies are striving to produce biologics more efficiently with a lower cost point and fewer employees. Most small-scale media and buffer operations are carried out with small bottles of liquid media. But as processes are scaled up to manufacturing levels, that is no longer a viable option. Costs of shipping liquid are simply prohibitive, so the industry has migrated to using media and buffers in powder form. In fact, 90% of cell culture media and buffers for sale is…

Virus-like particles (VLPs) have become a promising means for developing vaccines and gene therapies. Currently, vaccines based on VLPs are commercially available for human papillomavirus and hepatitis B and E. Other disease treatments with VLPs are undergoing clinical trials. Upon expression, the structural matrix polyprotein group-specific antigen (gag polyprotein) from the human immunodeficiency virus (HIV) has shown to accumulate beneath the lipidic membrane. After a sufficient number of gag polyproteins are recruited, the assembly process is finished, and the VLP…

Sartorius Stedim Biotech (SSB), a leading international supplier for the biopharmaceutical industry, has launched the BIOSTAT® RM TX single-use bioreactor, a new wave-action mixer system developed specifically for closed, automated expansion of consistent-quality cell therapies such as ex vivo cellular immunotherapies. This new good manufacturing practice (GMP) platform combines SSB’s established single-use Flexsafe® bag technology with the company’s expertise in biopharmaceutical automation.

Expansion of suspension cell culture from cell bank to bioreactor is performed through passages of successively larger Erlenmeyer shake flasks. A traditional cap must be unscrewed for each fluid transfer. Risk of contamination is mitigated by performing these fluid transfers in a biosafety cabinet (BSC) or laminar flow hood. Work in a BSC is not preferred because of high maintenance and operating costs, intensive cleaning and decontamination procedures, and the inconvenience of performing operations in the BSC. Despite the use…
