From: Sperm-derived histones contribute to zygotic chromatin in humans
Presence of histone H3 variants in human sperm. Human sperm, treated with heparin to induce chromatin decondensation, stained with a pan-H3 antibody (a), which recognizes all histone H3 variants (H3.1, H3.2 and H3.3) or a H3.1/H3.2-specific antibody (b) revealed for both antibodies a diffuse, global staining. The merge (c) with DAPI, which labels DNA, shows the nuclear localisation of the histones.
