Number of assays used to assess cell proliferation in publications of high ranking cancer journals; publications were counted from January 1995 to July 2009. A total of 60% of all researchers applied the listed assays to measure cell proliferation. Values for MTT/MTS were assessed through reading the abstracts of Medline articles retrieved through a ‘Google Scholar’ search. In the groups of WST-1, AlamarBlue, PicoGreen and CyQuant every publication was checked individually for the application of those assays.
