Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, IHC-P=Immunohistochemistry (Paraffin), F=Flow Cytometry, ChIP=Chromatin IP,

Homology

Species predicted to react based on 100% sequence homology: Mouse, Hamster, Pig,

Specificity / Sensitivity

Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb recognizes endogenous levels of histone H3 protein only when acetylated at Lys18. This antibody does not cross-react with other acetylated histone proteins.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding acetylated Lys18 of human histone H3 protein.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded breast adenocarcinoma using Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb in the presence of non-acetyl-Histone H3 peptide (left) or acetyl-Histone H3 (Lys18) peptide (right).

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded transitional epithelial carcinoma of the bladder using Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa and C6 cells, untreated (-) or treated (+) with Trichostatin A (TSA) #9950 (1 μM, 18 hr), using Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb (upper) and Histone H3 (D1H2) XP® Rabbit mAb #4499 (lower).

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 10 μl of Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human GAPDH Exon 1 Primers #5516, SimpleChIP® Human RPL30 Exon 3 Primers #7014, SimpleChIP® Human MyoD1 Exon 1 Primers #4490, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of Jurkat cells using Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb and Propidium Iodide (PI)/RNase Staining Solution #4087 to measure DNA content. Anti-rabbit IgG (H+L), F(ab)'2 Fragment (Alexa Fluor 488 Conjugate) #4412 was used as a secondary antibody.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded colorectal adenocarcinoma using Acetyl-Histone H3 (Lys18) (D8Z5H) Rabbit mAb.

Background

The nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), is the primary building block of chromatin. Originally thought to function as a static scaffold for DNA packaging, histones have now been shown to be dynamic proteins, undergoing multiple types of post-translational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (1,2). Histone acetylation occurs mainly on the amino-terminal tail domains of histones H2A (Lys5), H2B (Lys5, 12, 15, and 20), H3 (Lys9, 14, 18, 23, 27, 36 and 56), and H4 (Lys5, 8, 12, and 16) and is important for the regulation of histone deposition, transcriptional activation, DNA replication, recombination, and DNA repair (1-3). Hyper-acetylation of the histone tails neutralizes the positive charge of these domains and is believed to weaken histone-DNA and nucleosome-nucleosome interactions, thereby destabilizing chromatin structure and increasing the accessibility of DNA to various DNA-binding proteins (4,5). In addition, acetylation of specific lysine residues creates docking sites for a protein module called the bromodomain, which binds to acetylated lysine residues (6). Many transcription and chromatin regulatory proteins contain bromodomains and may be recruited to gene promoters, in part, through binding of acetylated histone tails. Histone acetylation is mediated by histone acetyltransferases (HATs), such as CBP/p300, GCN5L2, PCAF, and Tip60, which are recruited to genes by DNA-bound protein factors to facilitate transcriptional activation (3). Deacetylation, which is mediated by histone deacetylases (HDAC and sirtuin proteins), reverses the effects of acetylation and generally facilitates transcriptional repression (7,8).
