  • Saturation Density

    The maximum number of cells attainable per cm2 (monolayer culture) or per ml (suspension culture) under specific culture conditions.

  • Sc

    Stock culture, Laboratory of Enteric Pathogens, HPA Centre for Infections, London, UK

  • SDM

    Schneiders Drosophila Medium

  • Seeding Density

    The number of cells either per cm2 (if an adherent cell line) or per ml (if a suspension cell line) that are resuspended in a fresh flask after subculture. The recommended seeding density suggested by ECACC reflects the limits of a cell line to survive a split (ie. too low and there will not be a large enough population to successfully colonise the flask, too high and insufficient nutrients and space will be available for growth of any considerable length of time)

  • Senescence

    The point at which a cell or cell culture terminally ceases to grow.

  • Serum-Free Medium

    Specialised medium that contains additional supplements and growth factors so that cells can grow in the absence of animal sera. It is still the case that only cells adapted to serum-free growth will prosper in serum-free media.

  • SLCC

    H P R Seeliger Listeria Culture Collection, Wurzburg, Germany

  • SLSR

    See Std L

  • SMEM

    Spinners Modified Minimum Essential Medium

  • Somatic Cell Hybrid

    The cell resulting from the fusion of animal cells derived from somatic cells that differ genetically.

  • SRL

    Staphylococcus Reference Laboratory (Laboratory of Hospital Infection), London, UK

  • SS

    Statens Seruminstitut, Copenhagen, Denmark

  • Std L

    Standards Laboratory (became Division of Microbiological Reagents and Quality Control), London, UK

  • STH

    St Thomas's Hospital, London, UK

  • Subculture

    The transfer of cells from one culture vessel to another. Cells are usually diluted at subculture for continuous growth

  • Suspension Cell Lines

    Cells that do not require anchorage in order to grow.

  • Synkaryon

    A hybrid cell that results from the fusion of the nuclei it carries.
