ABSTRACT
A protocol for the simultaneous visualization of minor and major satellite DNA by primed in situ DNA synthesis (PRINS) was developed in cytokinesis-blocked murine splenocytes. After individuation of optimal experimental conditions, a micronucleus (MN) test was carried out by treating splenocytes in vitro with the clastogenic agent mitomycin C and the aneugenic compound Colcemid. It was found that PRINS gives highly reproducible results, also comparable with the literature on MN results obtained by fluorescent in situ hybridization (FISH). Therefore the PRINS methodology may be proposed as a fast alternative to FISH for the characterization of induced MN.
