Introducing Supor Prime Filters: A Filtration Solution for High-Concentration Therapies
This trend towards higher concentration is a challenge for existing filters due to the higher particulate load and viscosity. It is harder to process fluid through the filter and it clogs faster. Manu…

Commercial Production of Gene Therapies Using Suspension or Adherent Cell Lines
An advantage of FBRs is that because cells are in higher concentration than in STR at seeding due to the lower volume of the vessel, less are needed for inoculation, which reduces the operational burd…
