Application Notes
Applications Validated by Active Motif:
ChIP: 5 - 10 µg per ChIP
ChIP-Seq: 5 - 10 µg each
ICC/IF: 0.5 µg/ml dilution
WB*: 0.2 - 1 µg/ml dilution
This histone variant can be perturbed by excessive washing steps prior to fixation. Cells should be washed into serum free culture medium (NOT PBS) prior to fixation.
*Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.

Immunogen
This Histone H2A.Z antibody was raised against a peptide derived from the C-terminus of human histone H2A.Z.
Buffer
Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic. For your convenience, an unpurified serum version (Catalog No. 39113) of this antibody is also available.

Histone H2A.Z antibody (pAb) tested by ChIP-Seq.
ChIP was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with 30 μg of chromatin from a human medulloblastoma cell line and 4 μl of antibody. ChIP DNA was sequenced on the Illumina HiSeq and 18 million sequence tags were mapped to identify H2A.Z occupancy. H2A.Z is found throughout the genome, is often enriched at promoters and depleted from transcribed genes as shown in the images.

Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and HeLa Chromatin (1.5 x 106 cell equivalents per ChIP) using 10 µg of Histone H2A.Z pAb or the equivalent amount of rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primer pair specific for the indicated gene. Data are presented as Fold Enrichment of the ChIP antibody signal versus the negative control IgG using the ddCT method.

Nuclear extract of HeLa cells (25 μg) probed with Histone H2A.Z antibody (pAb) (1 µg/ml). Specificity was verified by peptide competition. Lane 1: no peptide. Lane 2: 1μm immunizing peptide.
Histone H2A.Z antibody (pAb) tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H2A.Z antibody for Histone H2A.Z. Recombinant proteins were spotted onto PVDF and probed with Histone H2A.Z antibody at a 1 µg/ml dilution. The amount of peptide spotted (in picomoles) is indicated next to each row.
Lane 1: Recombinant H2A.
Lane 2: Recombinant H2A.Z.

Background
The nucleosome is the smallest subunit of chromatin and consists of 147 base pairs of DNA wrapped around an octamer of core histone proteins (two each of Histone H2A, Histone H2B, Histone H3 and Histone H4). Histone H1 is a linker histone, present at the interface between the nucleosome core and DNA entry/exit points; it is responsible for establishing higher-order chromatin structure. Chromatin is subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; they play a major role in regulating gene expression.
Histone H2A.Z (H2AZ, H2AFZ) is a histone H2A variant, a protein similar to canonical H2A but with different molecular identity and unique functions. H2A.Z is highly conserved during evolution. It plays an important role in basic cellular mechanisms such as gene activation, chromosome segregation, heterochromatic silencing and progression through the cell cycle. H2A.Z is acetylated at multiple lysine residues in its amino terminus, which may enable H2A.Z to function as an insulator of chromatin domains.
