Date Feb. 2, 1984.Method for the performance of a mutagenicity test so that a cell population is subjected to a mutagen. As a result of this, a part of the population mutates, whereat the originally uniform cell population is differentiated into sub-populations. The variation of turbidity caused by the increase in the density of the differentiated cell populations is measured as a change in optical density by means of a photometer measuring vertically at a certain wavelength, and the quantity of cells in the sub-populations is determined as optical density. The absorbance values are measured in accordance with a pre-programmed time share system and a growth curve is formed out of the values as a function of time. |
