This Histone H3 acetyl Lys27 antibody was raised against a synthetic peptide including acetyl-lysine 27 of human histone H3.
PBS pH 7.5 containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic. For your convenience, a PBS only version of this antibody is also available.
Histone H3 is one of the core components of the nucleosome. The nucleosomeis 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). 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; these modifications play a major role in regulating gene expression.
Lysine 27 of histone H3 can also be mono-, di- or trimethylated by different histone methyltransferases, such as EZH2 or NSD3. While histone methylationcan be associated with transcriptional activation or repression, methylation of Lysine 27 of histone H3 is mainly associated with transcriptional repression.
Active Motif's HeLa acid extract (Sodium butyrate treated) (Catalog No. 36202) can be used as a positive control for Histone H3 acetyl Lys27 mAb (Clone MABI 0309).

Bridging Antibody to Improve ChIP, MeDIP and IP
Some isotypes of mouse IgG antibodies do not bind well to protein G-conjugated agarose/magnetic beads, which are commonly used in ChIP, MeDIP and IP experiments. Capture efficiency can be improved by including an anti-mouse IgG bridging antibody because it binds with a strong affinity to both the protein G beads and the mouse IgG antibody. By increasing the affinity of the mouse primary antibody for the protein G bead, the Bridging Antibody for Mouse IgG can help improve the results of all ChIP, MeDIP and IP experiments that use Histone H3K27ac antibody (mAb).
Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP). Visit our Secondary Antibody Conjugates page to find the perfect secondaries for immunofluorescence experiments with Histone H3K27ac antibody (mAb).
Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
This product is guaranteed for 6 months from date of receipt.
