Merck Millipore Introduces CellPrime™ Recombinant Human Lysozyme for Increased Protein Recovery From E. coli Production Systems
  • Provides five-times-higher protein recovery compared to animal-derived lysozyme
  • Gentle lysing agent minimizes risk of denaturing protein
  • Reduces regulatory concerns regarding animal-derived raw materials and risk of adventitious agents

March 1, 2012, Darmstadt, Germany — Merck Millipore, the Life Science division of Merck KGaA* of Darmstadt, Germany, today announced the launch of CellPrime™ recombinant human lysozyme for increased recovery efficiencies in biopharmaceutical production. Especially suited for lysing Micrococcus and E. coli, it delivers a five-fold increase in target protein recovery as compared with animal-derived lysozyme, the version commonly used in production. The increased efficiency offered by CellPrime™ recombinant human lysozyme, combined with high activity levels, results in a reduction of overall production costs when compared with animal-derived lysozyme.

While proteins are typically expressed in E. coli at high levels, extraction of functional protein is a critical step in the bioproduction process. Successful recovery is dependent on effective extraction methods such as disruption of bacterial cells by lysozyme or other enzymatic means.

“Use of animal-derived lysozyme for extracting protein therapeutics has significant drawbacks, including high lot-to-lot variation,” describes Janmeet Anant, Ph.D., Global Product Manager for Cell Culture Supplements. “In contrast, CellPrime™ recombinant human lysozyme is a more active cell lysis reagent, from non-animal origin, and is more consistent by virtue of being recombinant. As a result, it delivers increased protein yield while reducing regulatory concerns around animal-derived raw materials and risk of adventitious agents.”
