Fig. 6. Relative binding intensity of histone H2A-derived polypeptides to the lamin Dm₀ tail domain. The relative average intensity was calculated from three to six independent blot overlay experiments and was compared to that of the full-length histone H2A. The blot overlays reaction products were visualized with an ECL western blotting detection system and a luminoimage analyzer (LAS-1000 plus). Densitometric quantification was performed using the Science Laboratory 99 Image Gauge software. Bars indicate the standard deviation.
