Evaluation of the efficacy of the in vitro micronucleus method using a commercial kit and comparison with the microscopy method

Resumo

In vitro micronucleus testing  is an important tool in the investigation of the genotoxic potential of products. Performing the test by the optical microscopy method requires training and attention from the technician reading the slides and can be an extremely slow process.  The technique of micronucleus analysis by flow cytometry emerges as a highly complex assay that makes it possible to increase the number of analyses and reduce the time spent on experiments. Some commercial kits are sold to perform this test, however, in some cases, they can be very costly for the laboratory. This work demonstrated that the technique of micronuclei  in vitro by microscopy and cytometry are equivalent and that it is also possible to optimize the use of commercial reagents to reduce costs.
