Summary

As cells reach confluency, they must be subcultured or passaged. This video will demonstrate a procedure for subculturing both adherent and suspension cells.

Abstract

As cells reach confluency, they must be subcultured or passaged. Failure to subculture confluent cells results in reduced mitotic index and eventually in cell death. The first step in subculturing is to detach cells from the surface of the primary culture vessel by trypsinization or mechanical means. The resultant cell suspension is then subdivided, or reseeded, into fresh cultures. Secondary cultures are checked for growth and fed periodically, and may be subsequently subcultured to produce tertiary cultures. The time between passaging of cells varies with the cell line and depends on the growth rate.

Protocol

The complete text protocol for this experimental approach is available in Current Protocols in Cell Biology.

  4. sir can u tell me that how to transfer cell ( frozen into liq. nitrogen) into media and that will be the mother culture so in that also we have to do passaging , means we have to add HBSS and Trypsin and EDTA. and how to count cells. thank you waiting for your reply.... sam A Masih

  5. Hi, For subculturing suspension cells, what is the normal routine? is it better if changed everyday or only after the media contents turns trubid and yellowish colour? Regards Kamal

  8. Could you elaborate on how to culture cancer cells? The precautions to be taken and when to subculture them. Thank you

  11. every time I trypsinize my BBe cells - they clump together (even I don't shake the flask at all..)
    how can I prevent it ? because the clumps are super strong and I can not brake them down again.. I do something wrong?
    I wash ²x with PBS (37C) and 5-15min trypsinize the cells and add RPMI 1640 media carefully to it and mix gently..

    can you help me?

    thank you

  13. How long dŒs it take for an MCF-7 cell lines grow confluent? What's the best media for culturing this cell?
    Thanks!
