WebWorking Cell bank (WCB) Master seed vials are used to inoculate the HPV Shakeflask Medium. Future working seeds will be manufactured using the same process steps and similar equipment used for the original working seed. Following freezing, seed supplies are stored at ≤-60 °C. End of Production Cells (EOP) WebFor pharmaceutical use, it is necessary to test cells at the beginning (i.e., the cell bank) and at the end of production (end of production cells [EPC]). Thus it can be assured that the cell line has an appropriate level of stability and that adventitious agents are not introduced during, or induced by, the production process.
WebGenerally, the production cells are obtained by expansion of the Working Cell Bank; the Master Cell Bank could be used to prepare the production cells with appropriate justification.
