plaque-forming unit (medicine)


plaque-forming unit
<virology> Number of infectious virus particles or Ig producing cells per unit volume.

See: plaque assay.

<microbiology> Refers to any entity which can give rise to a plaque. For example: if a phage stock solution has 1010 pfu/ml, it means that every ml of this stock has 1010 phage particles which can form plaques. This (pfu/ml) is the conventional way to refer the concentration of a phage preparation.

Compare: CFU.
