  • Purification Of mRNA By Affinity Chromatography On CIMmultus® Oligo dT Column

    Increasing demand for messenger RNA (mRNA) as therapeutic product requires efficient and scalable purification methods. In this application note a CIMmultus® Oligo dT, a monolithic stationary phase is used for purification of mRNA from a capping mix of Luc2 RNA. The large channels and convective mass transfer within the stationary phase eliminate shear forces and allow high flow rates, which leads to very short purification times and high recoveries.

    The biopharmaceutical industry is looking at process intensification as a means to cost-effectively produce monoclonal antibodies (mAbs). This article explores intensified processing of Chinese hamster ovary clones in the seed train of upstream cell cultures to support generation of high-cell-density cell banks and increased production of mAbs.

  • Bioprocess Intensification – Fast, Flexible And Efficient Solutions

    Now that the biopharmaceutical industry has embraced single-use systems, the focus is shifting to process intensification, which has been defined in many ways. This compilation of articles details how Sartorius experts define process intensification and how end users can transition toward continuous processing.

  • Real World Experience: Modular Facilities, Smaller Footprint With Dynamic Perfusion

    Established manufacturers are looking to single-use, flexible solutions when building new facilities or modifying existing operations. Their goal is to increase productivity across different modalities, including difficult-to-express molecules. Read this success story to understand how dynamic perfusion enabled a CDMO to increase throughput dramatically while establishing a multi-modality facility.

  • No, Biologics Are Not Natural Monopolies

    Biologics are not natural monopolies, as certain individuals continually assert. This assertion threatens future innovations, greater healthcare affordability, and patient access. This article, backed up with data, debunks the myth that biologics are natural monopolies.


Biosimilars are considered to be low-cost substitutions for pricy, large-molecule biologics. However, biosimilars must meet the same quality, safety, and efficacy as their reference biologic. Manufacturing biosimilars requires a more complicated procedure than that of manufacturing small molecule generics. Companies manufacturing biosimilars are focused on creating a chemical structure that is as close as possible to that of the reference product. Failure rates and operational costs pose a challenge for those companies involved in manufacturing biosimilars compared to those manufacturing small molecule generics.

Small molecule generics are created using the same active pharmaceutical ingredient (API) and, therefore, are chemically identical to that of the originator medicine. The manufacturing process for small molecules comprises only one-fifth of the total in-process tests required to meet Good Manufacturing Practice compared to that of biologic medicines (50 vs. 250 in-process tests). In fact, the manufacturing process for a large molecule is so complex, it cannot be duplicated by two different manufacturers, as the cells used in biologic medicines are unique to the company manufacturing each biologic.

Manufacturing a biologic consists of genetically modifying a cell, which becomes the basis for a cell line used for the production of the necessary protein for the biologic medicine. The protein is then separated from the cells and purified. Biosimilars are created from small alterations to the manufacturing process which creates a molecule that is not identical but closely resembles the reference product. While the differences in the biosimilar molecule might be slight, these changes in the manufacturing process of a biosimilar can affect the efficacy and safety of a biosimilar compared to the reference biologic. Over the past decade, the manufacturing process for proteins has become more standardized and the required technology has become increasingly accessible, leading to reductions in biosimilars production costs. As a result, a greater number of companies have begun manufacturing biosimilars, while reference brand manufacturers are setting their sights on bolstering pipelines and manufacturing biobetters to maintain market share for their soon-to-be-off-patent reference products.
