常规说明
Mouse: Prominent staining of a subset of centromeric or pericentromeric heterochromatin. Interphase: The cells within the culture show a considerable variability in the intensity of staining with the antibody. The relationship between trimethylation levels and cell cycle have not yet been determined but may be a contributor to the amount of methylation detected in each cell. Heterochromatic regions of the interphase nucleus are the primary sites of trimethylation observed by indirect immunofluroescence. Mitosis: Discrete chromosomal regions are labelled intensely, with lower level fluorescence throughout the remainder of the chromosome arms. Immunofluorescence staining was performed as part of the nuclear antibody characterisation program at www.cellnucleus.com. Trimenthylation at Lys20 of Histone H4 isa common hallmark of human cancer (Fraga et al. 2005).

Primary antibody说明
In immunofluorescence: Human cells: The antibody stains a subset of cellular chromatin that is characteristically DAPI-rich (condensed, heterochromatic). The perinucleolar heterochromatin is particularly rich in trimethylated lysine 20 staining. Mouse: Prominent staining of a subset of centromeric or pericentromeric heterochromatin. Interphase: The cells within the culture show a considerable variability in the intensity of staining with the antibody. The relationship between trimethylation levels and cell cycle have not yet been determined but may be a contributor to the amount of methylation detected in each cell. Heterochromatic regions of the interphase nucleus are the primary sites of trimethylation observed by indirect immunofluroescence. Mitosis: Discrete chromosomal regions are labelled intensely, with lower level fluorescence throughout the remainder of the chromosome arms.

功能
Core component of nucleosome. 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. -
序列相似性
Belongs to the histone H4 family. -
翻译后修饰
Acetylation at Lys-6 (H4K5ac), Lys-9 (H4K8ac), Lys-13 (H4K12ac) and Lys-17 (H4K16ac) occurs in coding regions of the genome but not in heterochromatin.
Citrullination at Arg-4 (H4R3ci) by PADI4 impairs methylation.
Monomethylation and asymmetric dimethylation at Arg-4 (H4R3me1 and H4R3me2a, respectively) by PRMT1 favors acetylation at Lys-9 (H4K8ac) and Lys-13 (H4K12ac). Demethylation is performed by JMJD6. Symmetric dimethylation on Arg-4 (H4R3me2s) by the PRDM1/PRMT5 complex may play a crucial role in the germ-cell lineage.
Monomethylated, dimethylated or trimethylated at Lys-21 (H4K20me1, H4K20me2, H4K20me3). Monomethylation is performed by SET8. Trimethylation is performed by SUV420H1 and SUV420H2 and induces gene silencing.
Ubiquitinated by the CUL4-DDB-RBX1 complex in response to ultraviolet irradiation. This may weaken the interaction between histones and DNA and facilitate DNA accessibility to repair proteins. Monoubiquitinated at Lys-92 of histone H4 (H4K91ub1) in response to DNA damage. The exact role of H4K91ub1 in DNA damage response is still unclear but it may function as a licensing signal for additional histone H4 post-translational modifications such as H4 Lys-21 methylation (H4K20me).
Sumoylated, which is associated with transcriptional repression. -

Chromatin was prepared from U2OS cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 µg of chromatin, 6 µl of ab9053 (blue), and 20 µl of protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach). Primers and probes are located in the first kb of the transcribed region.

Immunohistochemical staining of paraffin embedded, PFA fixed, mouse liver using ab9053 at 1/100. Heat mediated antigen retrieval was performed using sodium citrate buffer, pH 6, and the sample was permeabilized with 0.05% Triton X 100. The sample was blocked in 5% BSA for 1 hour at room temperature and was then incubated with primary antibody for 3 hours in PBS/0.05% Triton X 100 at room temperature. An Alexa Fluor® 555 donkey anyti-rabbit was used as the secondary at 1/250.

ab9053 is specific for Histone H4 (tri-methyl K20). This is illustrated in lane 5 where the activity of ab9053 is specifically blocked by the addition of the immunizing peptide (ab17567).

IHC image of Histone H4 (tri methyl K20) staining in Human normal skin formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab9053, 0.2µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
