High Productivity Harvest

High Productivity Harvest (HPH) is a novel application developed by Repligen that enables you to harvest a fed-batch bioreactor in a fully sterile manner, while eliminating both centrifugation and depth filtration operations typically used for harvest/clarification. A single stage, closed process using the XCell ATF® device, the HPH application provides:

  • Higher yields compared to traditional harvest technologies

  • Up to a two-fold increase in protein production

  • A 0.2µm clarified harvest ready for either batch or continuous chromatography
