The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Use a concentration of 1 µg/ml. Detects a band of approximately 17 kDa (predicted molecular weight: 13 kDa).
Use 1µg for 106 cells. ab18536-Rat monoclonal IgG2b, is suitable for use as an isotype control with this antibody.
Is unsuitable for ICC/IF.
Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. May be involved in the formation of constitutive heterochromatin. May be required for chromosome segregation during cell division.
Belongs to the histone H2A family.
Monoubiquitination of Lys-122 gives a specific tag for epigenetic transcriptional repression. Acetylated on Lys-5, Lys-8 and Lys-12 during interphase. Acetylation disappears at mitosis. Monomethylated on Lys-5 and Lys-8 by SETD6. SETD6 predominantly methylates Lys-8, lys-5 being a possible secondary site. Not phosphorylated.

ab80150 (1/1000) staining Histone H2A.Z in paraffin-embedded Human pancreatic cancer tissue. Tissue underwent fixation in formaldehyde, peroxidase blocking, protein blocking and heat mediated antigen retrieval. After the primary antibody incubation a rabbit anti-rat link was used before the application of the secondary antibody which was goat anti rabbit/mouse conjugated to HRP. For further experimental details please refer to abreview.
Overlay histogram showing HeLa cells stained with ab80150 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab80150, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rat IgG (H+L) (ab98386) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rat IgG2b [RTK4530] ab18541, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
