2.
Prepare sample.
3.
Reactivate preserved bacteria as described in package circular and add 0.4 ml to
the zero cuvette and the sample cuvette.
4.
Select the evaluation mode <Test> and the TOX cuvette test <488> for LCK488
on the LUMIStox 300.
5.
Measure the initial luminescence of the zero cuvette and the sample cuvette.
6.
Quickly add 0.4 ml zero-solution or sample to the bacteria suspensions.
7.
Wait for the incubation period of 15 minutes to elapse.
8.
Measure the final luminescence of the “NULL” cuvette and sample cuvette.
