XD® Technology

DSM Biologics has developed a highly intensified cell culture process termed XD®, which provides cells with a constant environment for optimal cell growth (Figure 1). The XD® Technology works in a continuous media feeding mode with a filtration unit to retain both the cells and the recombinant protein in the bioreactor. Compared with a standard fed-batch process, the feeding regime in the XD® process can be performed with basal media, and this allows straightforward implementation without the need for extensive…

Formulation and Fill for a Vaccine with Alum Adjuvant

The goal: Develop a CGMP formulation–fill process for a subunit vaccine–aluminum adjuvant complex. The challenge: To engineer a scaled-up process for vaccine–adjuvant suspension formulation and fill, ensuring a uniform fill per dose as well as a sterile product. The Outcome: Florida Biologix scientists successfully developed the manufacturing, formulation–fill process and test methods. The process was conducted successfully in a scaled-down engineering run and at full scale, and 2,500 vials were tested, released, and shipped to the clinic on time. About…

Improved Capture with Better Productivity in MAb Bioprocessing

Growing commercial demand for therapeutic monoclonal antibodies (MAbs) has increased the need for efficient and cost-effective manufacturing processes. The development of cell cultures with very high expression levels is one clear example. over recent years, the antibody titers of mammalian cell culture have risen dramatically, and today we often see titers of 5–10 g/L. Expression levels as high as 15 g/L or greater have even been reported. Chromatography media (resins) that can capture these high-titer antibodies are therefore essential for…

Optimization of Conditions for Producing Influenza Virus in Cell Culture Using Single-Use Products

          Traditional influenza vaccine production uses fertilized hen eggs. This method is labor-intensive and requires large facilities with limited scalability. A switch to cellculture–based vaccine production methods and use of disposable products would provide flexibility to substantially reduce the time to vaccine clinical trials and approval, effectively decreasing the time-to-market. The aim of this work was to establish a process to propagate influenza virus in Vero cell culture using animal-component–free conditions for cell growth and disposable…
