Master and Working Cell Bank Generation

Portable CMC® Work Package 4

Wheeler Bio performs master cell banking as a stand-alone service, or as a module (Work Package 4) in our Portable CMC® offerings. The development of a master cell bank (MCB) ensures a traceable and consistent lineage for your cell line that will serve as the material basis for your drug development. Due to the critical nature of this milestone, Wheeler’s cell banking suite utilizes automation and single-use equipment to optimize efficiency and avoid any possible threats to cell bank purity. To complement these processes, our master cell bank development services also include real-time monitoring of incubators and freezer conditions through OSI PI Historian and temporary on-site storage of up to 300 MCB vials. Wheeler Bio also provides WCB generation and testing services with bank sizes of more than 300 vials.

For this crucial CMC milestone, Wheeler utilizes the highest-quality development and storage equipment within our manufacturing core including:

  • Nuaire Grade A Biosafety Cabinets
  • Eppendorf® New Brunswick™ S41i CO2 Incubator Shakers
  • -20°C and -80°C Thermo Fisher Ultra-Low Control Rate Freezers
