title: Destaining effects of immersion oils on Giemsa-stained chromosomes (R-bands).
abstract: In 24-48 hours, immersion oils without PCB (polychlorinated biphenyl) destroy Giemsa-stained chromosomes (R-bands) on uncovered slides. We can recommend yellow paraffin oil as immersion oil. It has a preserving effect on the chromosomes like immersion oils containing PCB.
