Formalin-fixed, paraffin-embedded human colon cancer tissue stained for Histone H2A.X(Phospho Ser139) using 12162 at 1/100 dilution in immunohistochemical analysis.
Immunocytochemistry/Immunofluorescence Histone H2A.X(Phospho Ser139) antibody (12162) ICC/IF staining of Histone H2A.X(Phospho Ser139) in Hela cells. Cells were fixed with 4% Paraformaldehyde permeabilized with 0.1% Triton X-100. Samples were incubated with 12162 at a working dilution of 1/100. The secondary antibody was Alexa Fluor® 647 goat anti mouse, used at a dilution of 1/500. The negative control is shown in bottom right hand panel - for the negative control. Nuclei were counterstained with DAPI.
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene encodes a replication-independent histone that is a member of the histone H2A family, and generates two transcripts through the use of the conserved stem-loop termination motif, and the polyA addition motif.
