Confocal imaging of haploid and diploid HAP1 cells showed large ploidy-dependent differences. Ploidy-verified haploid and diploid HAP1 cells subjected to immunocytochemistry and imaged with a confocal microscope. (A) Overview of cell culture as observed with 40× objective (left) and 100×objective (right). Nuclei were visualized with DAPI and F-actin with fluorescent phalloidin. (B) A closer look at structures in single cells (3×optical zoom, 100×objective). Nuclei and F-actin were stained as in A. In addition, mitochondria were visualized with antibody towards Cox IV and microtubules with antibody towards β-tubulin.
