    A high capacity, high throughput strong anion exchange chromatography membrane designed for single-use per batch biomolecule purification. The unique Natrix® Q membrane contains a high density of quaternary amine ligands that are directly polymerized within the porous membrane scaffold.


  • For CAR-T processes that require a freezing step between apheresis collection and manufacturing, it is critical upon thaw to remove Dimethyl sulfoxide (DMSO), a standard component of cryoprotectants, from the product to ensure the utmost cellular health of the apheresis material. In this application note, we demonstrate how the ekko™ Acoustic Cell Processing System consistently processes apheresis products.

  • Strong anion exchange (AEX) chromatography has become an industry standard in polishing steps for monoclonal antibody (MAb) purification. It is a proven technology to remove DNA, viruses, endotoxins and acidic host cell proteins (HCP) from process feed streams in flowthrough mode. This application note examines the performance of Natrix® Q chromatography membrane in comparison to currently available quaternary amine resins, membranes and salt-tolerant primary amine membranes.

  • MilliporeSigma’s new cell culture medium offers an improved alternative to classical formulations that can help address the constraints in viral vector manufacturing and scale-up.

  • Single-pass tangential flow filtration (SPTFF) can be used to achieve higher final concentrations, optimize product recovery, control volume of intermediate steps, and enable intensified or continuous processing with chromatography or filtration operations. This study demonstrates efficient cleaning strategies to enable multiple reuse of TFF cassettes for high concentration applications with SPTFF.

  • Lack of consistency in cell culture media can create significant variation in your upstream process. To control cell culture media variability and ensure the quality of our products worldwide we have implemented a robust supply process that incorporates a global raw material and vendor management program, a consistent manufacturing network, and global quality systems.

  • Traditional bioburden testing can take several days to show visible colonies. Earlier detection makes it possible to address fermentation contamination events sooner, avoiding reactor shutdowns and downstream problems. The Milliflex® Quantum system can quantitatively detect microbial contamination in filterable samples up to three times faster than traditional plate-based monitoring methods.

  • In biomanufacturing processes, mixing is ubiquitous and mixing trials are often necessary to assess if a technical solution is adapted for a given process step or to optimize process parameters. Discover how computational fluid dynamics can help in your mixing trials.

  • In this white paper, the use of 3D printing to overcome challenges during formulation development is explored, with a focus on enhancement of bioavailability of active pharmaceutical ingredients (APIs) in solid dispersions. It is estimated that 60–70% of drug substances currently in clinical pipelines are categorized as Class II in the Biopharmaceuticals Classification System (BCS) which indicates low solubility. For an oral formulation, the proper API solubility is critical for absorption in the gastrointestinal tract. If solubility issues cannot be overcome during formulation development, an otherwise promising therapeutic candidate may have to be abandoned.

  • Cell culture media are complex mixtures of synthetic and biological components that provide the proper composition of nutrients for healthy cell propagation and high protein expression. Key concerns are to ensure product safety and purity. This paper presents our recommended methods for thoroughly mixing media, as well as reducing the risk of mycoplasma contamination.
