If you have grown cells or used cells in your research, you know the problems associated growing them and in ensuring that they generate reproducible data. After obtaining or engineering a cell line, master and working banks must be produced. Supplies must be ordered. Technicians must spend hours under the hood. Sterility must be maintained. Cell cultures must be split and fed over and over again. Repeated cell counts and viability measures must be done. Cells must be harvested and aliquoted. The cultures must not contain any Mycoplasma contamination. Cell line IDs should be verified, etc.
