Fluorescence images of fixed control and SUV39H1-depleted (by SiRNA transfection) mitotic HeLa cells showing the distribution of SMC1 (cohesin marker, red) and Tripin (centromere marker, green). Cohesin localization at kientocheres but but not spindle poles is affected by Cells were observed with an Olympus IX70 microscope and recorded with a Magnaview CCD camera.
