We characterize Master Cell Bank (MCB) and Working Cell Bank (WCB) according to all applicable ICH guidelines, employing testing methods specific to the cell line used for your production. Cells are grown in the appropriate incubators, and microbial and mammalian cell banking activities are conducted in completely separate areas. We certify that mammalian cell lines are free of mycoplasma and bacterial contamination.
For risk mitigation, we store a portion of our clients’ MCBs and WCBs offsite under cGMP conditions, either in vapour phase of liquid nitrogen vessels or in deep freezers (-80º C), with a monitoring system to confirm proper liquid nitrogen levels and freezer temperatures at all times. Banks are separated and stored in individual freezers at two different locations to prevent loss due to freezer malfunction, and a fully redundant backup system ensures the security of the storage facility.
