Powerful tools supporting biopharmaceutical purification

Biopharmaceutical manufacturing processes have high costs. This is because a multi-step purification is required to separate the many components generated during the cell culture step. The manufacturing process is roughly divided into upstream processes, including cell culture, and downstream processes, including purification. Purification using chromatography in the downstream process includes three steps: initial purification (capture), intermediate purification, and final purification (polishing). In each step, the packing material (bulk medium) and chromatography device are chosen depending on the intended purpose. YMC provides products and services for biopharmaceutical purification, including packing materials (bulk media) and chromatography devices that can realize reduced process costs.

Quality control of biopharmaceuticals

Biopharmaceuticals, such as monoclonal antibodies (mAbs), contain impurities derived from the host cell and related substances, as they are often produced from cell cultures and are easily denatured compared with low-molecular-weight pharmaceuticals. For quality control, high-resolution columns are required to separate many of related substances, including isoforms. YMC's various product lineups, such as ion exchange columns and reversed-phase columns, which have high performance and high lot-to-lot reproducibility, are suitable for quality control.
