Eshmuno™ Resins for Biochromatography

          Eshmuno™ is a new and unique family of ion-exchange resins that are designed specifically for highly productive downstream bioprocessing. The first member of the family, Eshmuno™ S, is a smart cation exchanger designed for fast and efficient purification of antibodies in direct capture and steps following protein A chromatography. Eshmuno™ Q is the newest family member. This smart anion-exchange resin coupled Merck KGaA’s renowned tentacle structure with the new hydrophilic polyvinyl ether base matrix. As…

Eshmuno™ Resins for Biochromatography

Figure 1: Production of biopharmaceuticals has over recent years evolved from simple scale-up of lab-based techniques into a much more engineering-driven task. The entire industry has matured. Safety and efficiency are key drivers in this new era. Large and increasing production volumes of biopharmaceuticals create a need for further development of chromatographic stationary phases. The main focus of resin development has been to increase productivity, which can be achieved by a combination of improved pressure-flow resistance along with increasing the…
