HeLa cells were stained with the Bioss antibody against H4K5,8,12ac (cat. No. bs-53096R) and with DAPI. Cells were fixed with 4% formaldehyde for 10’ and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. Figure A: cells were immunofluorescently labeled with the H4K5,8,12ac antibody (left) diluted 1:500 in blocking solution followed by Alexa488 conjugated secondary antibody. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right. Figure B, C, D, and E: staining of the cells with the H4K5,8,12ac antibody after incubation of the antibody with 10 ng/μl of the following blocking peptides: H4K5,8,12 unmodified (figure B), H4K5,8,12ac (figure C), H2A.ZK5,7,11ac (figure D) and H4K5,8,12,16ac (figure E).
