Cell lines

Cell lines


Passage is usually between 25 and 30. Vircell may be able to provide younger passages (around 25) on request.
MRC-5 cells can be subcultured up to a passage of 40. The rest of lines can be subcultured indefinitely.

All cell batches are tested for Mycoplasma contamination at each stage of the manufacturing process and on the same day of shipment. Mycoplasma controls are carried out by Hoechst staining and culture in specific medium which is examined daily for 15 days. In addition, we check all our cell lines for Mycoplasma by PCR, every 6 months.
