Various pretreatments of metaphase spreads were examined to obtain optimal DNA labelling patterns while maintaining chromosome integrity during in situ hybridization procedures. Preparations of African green monkey (AGM) chromosomes fixed in methanol-acetic acid (CV-1 cell line) were treated by coating
