Working Cell Bank Development

Working cell banks (WCBs) are prepared from the MCB under defined cell culture conditions. Quality control tests, via DNA profiling techniques, are performed to confirm that the MCB and the WCB are genetically identical, as well as to ensure the WCB is free of contaminants.
